I am just getting started with trying to use deployment parameters. When creating a scheduled automation, I thought I could use cron in a scheduled automation trigger but store the cron details in a deployment parameter. I took a working cron configuration and stored those details in a deployment parameter. Then when trying to enable the automation I got this error message in the debug log: Unable to assemble automation. Invalid Cron expression: {deployment.Trap_Daily_CRON}I am selecting the deployment parameter from the menu when creating the cron configuration, not just typing this in so I had expectations that this would succeed.There doesn’t seem any way to get this working that I can see.Is this something that is actually available?This is on FME Flow Hosted 2025.1.3.

Hi! I’m trying to read dwg files containing AEC objects and have found that the Civil 3D reader should be the one to use for this purpose. With this reader, I manage to read features but they are just a proxy of the correct objects that I’m trying to read.Is there an automated solution for this in FME (some parameter that I’m missing?) or do I have to save the model in a separate dwg file as described in this post (8 years ago) before I can read all objects correctly in FME?Thanks!

I have a process in FME and I want to send an email with the Emailer transformer at the end. I've already written in the email body the data I want to appear in the email, but the problem is that I want to send it in plain text format and not in HTML. The Emailer transformer always wraps my text in HTML, even though I already changed it to FME's format; it seems that every time I exit the transformer to run the process, it doesn't save the text settings in the transformer. Does anyone know how to change this?

Hi,I have 79 single-band rasters, each a step in a time series, with Int8 values that reprepresent a risk class. I want to get the max value for each cell and use a RasterMosaicker to achieve that. Then I use a RasterToPolygonCoercer to convert to polygons for further analysis. My problem is that converting the raster from the RasterMosaicker is extremely slow and performance demanding compared to converting the individual raster I have before the mosaicker (the timesteps are converted in a matter of seconds whereas the mosaicked raster takes in the range of an hour or more). This is an example of my workspace:Why is it so much slower to convert the mosaicked raster? As far as I can see they have the same properties and dimensions. It does have more data but not by much and still most of the cells are nodata. Is there a faster way to achieve the same thing or am I missing something? Thanks! 

We have a distributed architecture of FME Flow 2025.1.2 using our own Tomcat deployment and we’re offloading our SSL via F5 into our private IP space. The issue we’re seeing is in the FME Flow REST API Gateway is the URL used in CURL/Request example URLs are http but should be https.We don’t believe its a CORS issue since we’re inside our domain. Where is FME Flow getting the CURL URL? Can we change it in a config file? Or is something else going on?

Hi all,I have a workflow in FME where I need to iteratively buffer a feature and check for neighbours, until no neighbour is found.The logic I want is roughly this: Buffer the feature by 10 m Use NeighborFinder to check if any neighbour exists If a neighbour is found, increase the buffer by 5 m Check again with NeighborFinder Repeat (increase buffer by 5 m each time) Stop when no neighbour is found and output that feature So the buffer distance sequence would be something like:10 m → 15 m → 20 m → 25 m → … until no neighbour exists  What is the recommended way in FME to build this kind of iterative / looping buffer logic?  Thanks in advance!

When people download data from us they get maps that have names about what kind of data they are downloading and not the names. Like the photo but under the folders there are the names that i can control (see blue circle). Does anyone know how to change this or just skip the folders and just let everything go to the same place? They have a demo for this for shapefiles where they go in the same folder but it cant be used for cad as it needs to use layer name not for naming files but for the layer name I want in the file. Also when you do this you get extra attributes from other files even if they are just empty. This is so in the demo from Safe here: https://support.safe.com/hc/en-us/articles/27400509041421-Data-Distribution-Tutorial 

Hello everyone,I’m working on an FME workspace where I need to process multiple input files sequentially within the same workflow, and I want to make sure that each file is processed independently, without any data or state being kept in memory from the previous file.Conceptually, what I’m looking for is a way to flush or reset the internal state between files, so that:cached features, temporary aggregates, statistics, or in-memory objectsfrom a previously processed file do not affect the processing of the next one.ContextI’m looping over multiple files (using a file-based workflow, not separate workspaces). The workflow includes transformers that may keep internal state (e.g. aggregations, statistics, grouping, geometry operations). The goal is to guarantee deterministic, per-file processing, similar to a “clean run” for each file.My questionsIs there a native way in FME to explicitly flush / reset the internal state of a workspace between input files? Are there specific transformers

Hi there!I get tons of these messages from some workspaces created with FME 2020 (in Norway) and now  migrated to FME 2024: The Startup Python Script changed the current FME process locale from 'Norwegian Bokmål_Norway.utf8' to 'C' and FME has restored it back to 'Norwegian Bokmål_Norway.utf8'. It is undefined behavior to change locale and doing so may cause unexpected errors. For more information, visit http://fme.ly/PythonLocaleErrorI have read the post http://fme.ly/PythonLocaleError carefully, but it does not give me anything. I have nothing such as import arcpy or locale.setlocale() in my Python-code. The example message above is particulary strange, I don’t even have a Python Startup Script. So something is absolutely confusing here.No Startup ScriptAnother example:PythonFactory script changed the current FME process locale from 'Norwegian Bokmål_Norway.utf8' to 'C' and FME has restored it back to 'Norwegian Bokmål_Norway.utf8'. It is undefined behavior to change locale and doing

Has anyone in the UK who is using the Ordnance Survey Maps API managed to get them added into FME for use as a background map.  I have tried and get nothing to display….Any advice welcome...

Hello FME TribeThanks to FME for organizing this 12 days treasure hunt! I was back to my school days trying to decipher code and spending hours together checking images 😃 This is regarding the first Image Puzzle that was asked in the 12 days FME contest. The compass in the image displays the year 2014 faintly on a compass. This was spotted by me and when I entered the value 2014 in the text box I always got a error message which read something like The entered value is in a date format that I am not aware of . That made me think that the expected value to be in conventional date format. Probably the message could have been more precise. At the same time, I can also see that many others have successfully answered that quiz.Did anyone face the same problem? Now that the contest is over, I just thought I can safely check whether others also faced the same problem.  RegardsGovind

I am reading the feature classes and tables from an Oracle Reader, and many of those are not having any records, the tables are empty. But I want all of those in my ESRI FGDB output which I am using in the Feature Writer dynamically. How to achieve this? Any leads?

Ever since the merging of SQLServer spatial and SQL Server non-spatial Reader types, my SQLCreators and SQLExecutors generate a warning:Microsoft SQL Server Reader: Table `___FME_Custom_SQL_Statement___' does not include a spatial column. Geometry will not be read In Form this is easily ignored, but it really messes up my Jobs overview dashboard on Flow, because it results in quite a lot of listings with warnings that do not need checking. And I can’t seem to find a way to tell FME that yes, I know, there is no geometry coming through in this sql, don’t worry about it because I did not select it - on purpose (or because it does not exist).I really do not want to turn off all warnings generically, I am just searching for a way to stop this particular warning. Before the merge it was easy: just use the non-spatial type, and the warning would go away. But that is not an option anymore unfortunately...  

Hi,I have a very simple workbench that is cliping a gpkg containing mulitple layer. I am struggling with writinng them back to one gpkg using dynamic schema. it fails every single time  

Hello,Our FME Flow server is installed behind a secure proxy and is accessible via the following URL: **[https://my.domaine.be](https://my.domaine.be)**The FME Flow server itself is *not* running in HTTPS; the HTTPS layer is configured at the proxy level.However, in the FME Flow configuration through the Web interface (Admin → System Configuration → Network & Email → Services), we have properly updated all URLs so that the root is **[https://my.domaine.be/](https://my.domaine.be/)**, and in “standard” usage everything works correctly with HTTPS URLs (access to the FME Flow web interface, data downloads, application publication, Webhook exposure).However, we are unable to use the REST API because an issue remains (see image in this email):FME seems to expect its API to be contacted over HTTP (see image in this email), whereas we must absolutely communicate with **my.domaine.be** over HTTPS.Could you tell us what needs to be adjusted in our configuration—whether at the proxy level (s

I’ve been struggling with the File Geodatabase Open API FeatureWriter in FME. When I create a new file geodatabase from scratch, everything runs successfully. However, when I switch the FeatureWriter to Drop and Create, I encounter random failures with the error:Geodatabase Error (-2147467259): General function failureHere’s my setup:The workbench consists of a series of Oracle SQLExecutors that read each table, followed by a FeatureWriter to convert the data into feature classes in the file geodatabase. I originally used a dynamic workspace, but after seeing this error (and reading advice to limit the number of features processed dynamically), I changed the design so each table is processed in series. The failures occur at different FeatureWriters each time, so it’s not tied to a specific table. I tried using Truncate instead of Drop and Create (since truncating is better for avoiding file locks), but it was very slow, so I abandoned that approach. As a workaround, I check for lock fi

I have images taken by a camera mounted on a vehicle, with GPS (4326) coordinates recorded every millisecond. I also have a road reference dataset in a shapefile (epsg :2154) and I need to match my millisecond-spaced images (and their GPS coordinates) to this road reference. There will obviously be some discrepancies between the GPS measurements and the reference dataset, but how can I best align the GPS data with the road reference? What is the best method to do this?If you’d like, I can also help you rephrase it more formally or technically.Thank you

My scope currently is to produce an excel output using FME ensuring the template is being leveraged to populate the values in this columns. Some of these columns have formulas which have been coded in FME as AK.formula if the column AK has formula. However when I convert the FME produced Excel to XML and investigated this, the formula seems to be converting “ into &quot. However I get to know about this only when I checked XML since Excel exactly imprints the formula as coded in FME. What is the best way to resolve this issue?

Hi, The workbench to convert the File geodatabase to CAD was working until the FME/ArcGIS upgrade. The workbench is now not writing many line features  with the following warning The following feature is not valid because its entity type of 'fme_no_map' and its geometry type of 'IFMELine' do not match. The geometry failed to be converted to match the type, so the feature will be skipped.  Warning : Attribute(string; UTF-8)           : `autocad_entity' has value `fme_no_map' FME version : FME(R) 2025.0.0.0 (20250228 - Build 25208 - WIN64) How can this be fixed? ThanksSresree

I have a raster broken up into a grid of raster cells using RasterTiler.  I want to rotate each cell X degrees (not the whole raster) in place.  I do *not* want to rotate around the upper left corner.  I need the cell to rotate and remain in the exact location.As I understand it, my process is using the following transformers:RasterCellOriginSetter: Set to 0.5,0.5 (the center) Rotator: Set Rotation Angle to X. RasterRotationApplier: Interpolation Type = Bilinear.When I do this, the cells are rotated around the upper-left corner rather than the centroid.Do I have the correct transformers & settings for this application?

On FME Flow we added a Network Based Resource. In FME Flow, I can see that the system path of this Network Based Resource is characterized with a parameter, e.g. '$(My_Network_Based_Resource)'. I had some trouble on using that parameter in a workspace with FME Form Workbench. FME Form is not aware that this parameter exists, and upon using it in e.g. a path reader.Is there any way that you can expose additional FME Flow parameters to FME Form Workbench? As a workaround I was able to use a ParameterFetcher, and then feeding in the attribute value of the Network Based Resource into the FeatureReader, but that seems not ideal. Also, the ParameterFetcher does show a Red Cogwheel, because it is not aware of the parameter. Another alternative is probably to create an additional 'FileURL' type of parameter, and set the (default) value for that parameter to '$(My_Network_Based_Resource)'. However, also here it seems that you are then forced to make the FileURL parameter

If there is an automation where a workspace with an automations writer, triggers a child workspace a number of times is it possible to restrict those jobs to run on the same engine without the use of a queue?I want all child jobs triggered from the writer to run on the same engine as each other for a single automation run, but i don’t necessarily want to say that jobs can only be run on a single engine, as would be the case if I set up a queue.

I got an error from FME 2019.2 and FME 2022.1. The error is " Python Exception <OSError>: Could not find a suitable TLS CA certificate bundle, invalid path: C:\\Program Files\\PostgreSQL\\15\\ssl\\certs\\ca-bundle.crt".Anyone has idea how to fix?

Hi,I’m relatively new to FME and currently doing some self-teaching for my company. At the moment, I’m trying to use an Excel Writer with a fanout expression to create hierarchical folders and files. The challenge is that I’m working with a bathymetric raster layer, and my workflow is primarily in CARIS, so the output files must be compatible with CARIS.I’ve tested several export options and found that .csv and .shp files work, but other formats do not. Does anyone have suggestions on alternative ways to create these folders and files while ensuring compatibility with .csar or caris compatible point cloud files?I also wonder if I am able to export contours as anything other than a shapefile/ can it be a .hob?My fanout expression is currently: @Value(ObjectName)Raw_Data\@Value(ObjectName)_BathymetricData.csv

Hello Forum, I have two polygon datasets read into a FME Form workspace: Dataset 1: Super Output Area (SOAs): This is where the entire authority area is divided into 165 SOAs. No part of our authority area is not covered by a SOA. Dataset 2: Air Quality Focus Areas (AQFAs): These are specific areas for a particular purpose. Only selected parts of the authority area are covered by an AQFA.  Datasets 1 and 2 are entirely different and do not share boundaries or nest etc. If that happens anywhere it is entirely coincidental. I need to know what percentage of each SOA intersects (overlaps) with an AQFA area. Some SOAs are going to be fully outside an AQFA. Some SOAs will be partially within an AQFA. Some SOAs will be fully within an AQFA. I want to know what percentage of each SOAs is within an AQFA. The results would be added as a new attribute to the SOA dataset as a percentage value (0-100). I know that using AreaOnAreaOverlayer I can chop up the SOAs where they intersect with AQFAs. Bu
