FME Form

Hey all, Currently having an issue using the ArcGIS Connector when using FME Flow (or Form without Feature Caching / Counting on), receiving the following error below. Full log posted below the error message. The outcome I am looking to produce is to update a CSV file hosted on an Enterprise Platform. This does run with form with feature caching on. Any help would be much appreciated.Thanks. Ash135 2025-11-14 17:25:19 | Message Type: fme::internal::_v0::py::Exception 136 2025-11-14 17:25:19 | Python Exception <TypeError>: Call to pyoutput() requires an output_tag argument when multiple output ports exist 137 2025-11-14 17:25:19 | Error encountered while calling method `input' 138 2025-11-14 17:25:19 | ArcGISOnlineConnector_2_CALLER (PythonFactory): PythonFactory failed to proc

Hi Everyone!I’m currently working on a workflow using a dwg file (water system) to convert it into a geodatabase. I was wondering if anyone has any tips on the transformers and workflow I could use to successfully do this? Right now I have my dwg reader as individual types, leading into an attribute filter, and geometry filter (3 different ones- 1 for water, drainage, and sanitary). These 3 end up writing into the geodatabase. I would like to have feature datasets separating water, drainage, and sanitary written in the geodatabase. I understand this is a big undertaking, but any tips (or perhaps links to guides) would be extremely appreciated! Thank you!

Hi, I have a list of 100+ WMS services our company is using in a plugin for QGIS. I’d like to publish these to our enterprise portal, and I thought the ArcGISOnlineConnector seemed like the right choice, due to it haven the setting:Action: UploadURL : WMS URL https://***.net/geoserver/dai/wms?service=WMS&request=GetCapabilities&version=1.3.0 URL Item Type: WMS ?  My error is :ERROR |Message Type: fme::internal::_v0::py::ExceptionERROR |Python Exception <TypeError>: expected str, bytes or os.PathLike object, not NoneTypeERROR |Error encountered while calling method `input'FATAL |ArcGISOnlineConnector_CALLER (PythonFactory): PythonFactory failed to process feature What have I misunderstood ? Or is there a better option ? Thanks in advance.  

Good morning.I’ve been testing lately a FME Flow 2024 version.When writing “Date” field types using the ArcGIS Online Feature Writer, the following warning masked as an error is thrown:D:\code\fme\source\engine\plugins\python\fme-arcgisonline\src\arcgisonlinefeatures\arcgisonlinefeatures_rest_writer_helper.py:557: DeprecationWarning: datetime.datetime.utcfromtimestamp() is deprecated and scheduled for removal in a future version. Use timezone-aware objects to represent datetimes in UTC: datetime.datetime.fromtimestamp(timestamp, datetime.UTC).The FME 2025 Change Log shows this entry:It only mentions the Reader. Would it be possible to know if that deprecation was solved for the Writer, too?Thanks!

Hello, I am attempting to copy an ArcGIS Server Feature Service from our Production portal to our Staging portal as a test migration using ArcGIS Data Interoperability (FME). The migration runs successfully, and the layer is created on the destination portal with all point features appearing correctly. However, every attribute field in the destination portal is empty for the layer.For this workflow, I used: Reader: Esri ArcGIS Server Feature Service Writer: Esri ArcGIS Portal Feature Service The strange part is that when I inspect the data immediately before the writer, all attribute values are present and correct in the Visual Preview. But once the writer publishes the layer to the portal, the attributes do not appear, only the geometry is transferred.Could you please help identify what might be causing t

I have a job that downloads 7 text files from an FTP directory, and for the last 3 days, 6/7 files have downloaded but 1 always fails (the same one each time) with the error: Number of redirects hit maximum amountI am aware of the post below, but as no similar setting exists on the FTP caller, I’m lost. I can upload fine, and manually downloading the files by logging into the FTP site, or using a WinSCP script also works. The file that failed today was empty (0MB), but so are some of the other files it downloads, and yesterdays file had records and still failed. Empty files are not uncommon for this job, and it has never presented an issue before. This has started occurring since upgrading to 2025.1.3 from 2022, and occurs on both FME Flow and Form. This error has so far not ap

I'm trying to use FME 2025.0 to create a GeoPackage tiles file. It should contain a few Norwegian raster products, such as N50, N100 and N250. The idea is to mimic the properties of the Swedish product “Topografisk webbkarta Nedladdning, raster”, in the sense that the Swedish product contains a single table in the gpkg file and it shows different raster data at different scales. I am having trouble recreating this with the Norwegian products. I´m stuck at creating a separate tables for each data set or a single table that only contains a single data set. This use case is not discussed at, for example, https://support.safe.com/hc/en-us/articles/37417604217357-Creating-OGC-Compliant-GeoPackage-Files#h_01JXXGG7338W04GD0DRBY7VJCV. Any help appreciated. Norwegian products: 

Hi  I have spent far too many hours trying to make the change detector dynamically pick up changes. The scenario is: I have 10 datasets that need to be compared between the original and updated databases. Each dataset has only a few fields that need to be checked for changes. These fields are different for each dataset. I have a CSV which is acting as a 'config' file and contains a list of the field names to check for each datasetI have 2 workbenches; the first workbench gets all of the information from the config file, then passes through the information via user-parameters to the Change Detection workbench via workspace runner. Even though I have created a user parameter for the "Match Selected Attributes" config in the ChangeDetector, I can't pass through this information via the workspace runner. It ONLY works if I run the Change Detection workbench individually, and this isn't linked to the

I have a workspace that is reading a table via the MS SQL JDBC reader and writing the output to an Esri File Geodatabase feature class. It works in FME Form. However, In FME Flow, it fails after the following message (not a warning or error) and shows 0 warnings/errors in the log:Writer `GEODATABASE_FILE_1' of type `GEODATABASE_FILE' using group definition keyword `GEODATABASE_FILE_1_DEFIf I read the same exact data in from a CSV file and write to the Esri File Geodatabase, it works in FME Flow. If I read from the MS SQL database and write to an Open API File Geodatabase, it also works. However, I need to use the Esri writer in production for updates due to some Esri-specific functionality. It seems that there is some sort of odd bug specifically when using the MS SQL JDBC reader and Esri File Geodatabase writer in FME Flow. Has anyone else run into this or have any suggestions?Notes: I’ve tried with

Hello, so we regularly download the whole catalogue of polygons for England, seen here:Dataset Download - Use land and property dataI would very much want to automate this as its a tedious task to manually download them all one by one, so I’ve investigated the calls that my browser makes when calling this data and it first sends a very simple call to very simple URL’s containing the Zipped data, as seen here:https://use-land-property-data.service.gov.uk/datasets/inspire/download/Amber_Valley_Borough_Council.zipWhich in turn takes you onward to a Amazon service that just gives you 60seconds to fetch the data, as seen here:

Hi, sometimes the XML Driven XML Writer decides that I have not set the Application Schema when I click on FeaturePaths edit button. As you can see it is set and the XSD file behind works well in a different workspace. But for some reason I get the error you can see in the attachment and I don’t know why. Starting a workspace from scratch works again with the same settings. Thank you for advice.

I have a lot of multipage PDF documents that I need to each summarize. Does anyone have any tips/experience/recommendations with working with multipage pdfs in FME and an AI of choice?I’ve played around with Copilot a bit and have got prompts to return pretty good results, but it seems like FME doesn’t natively support Copilot, so I’ll have to probably switch AI solutions. Thanks in advance!

Hi,I have run into behaviour in FME Form that I don't understand. I want to read an OGC API (WFS3.0) point features from any of these collections ( https://api.pdok.nl/lv/bgt/ogc/v1/ ) within a bounding box that I create based on input features.I dynamically create a bounding box (my random example: 6.7337723637079705,53.153741409492596,6.742906946412802,53.15869110582926 ) in a workflow before the FeatureReader.When I add the featurereader without any collection query parameters and save it so it generates the output port. And then I open the parameters and set bbox to the attribute value from the bbox (and also ‘limit’ to 1000). These parameters are not applied and used. Only when I regenerate the output port it applies any HARDCODED values. I cannot feed any dynamic value from a user parameter/attribute.If this is intended behaviour in FME: wh

HiSomething strange. I just wanted to write shapefiles with a fanout based on a field in the attributes, and that no longer works.  No errors, it creates the folders in the specified location but does not fill them.  It selects one and ignores the rest. I don't understand. I've used it a million times and never had any problems.  Has anyone else noticed this? Is it the version or is it me?

Hi,I recently moved to FME Form 2025.0.3 from FME Workbench 2021.1.2.The install is on a central windows machine. Some workbenches run as other users. ArcMap and ArcPro (3.4) are also installed on this machine.All our workbenches involve ESRI enterprise geodatabase readers or writers, so require an ESRI licence to run.Users of FME all have named user licences for ArcPro, they are able to launch Pro and obtain a licence on the central machine.When I use FME Form there is no issue accessing the ESRI licence and using the readers/writer. However when testing with other users, who have the same type of named user ESRI licence, FME reports the error: “Worker 6428 > Unable to perform any licensing related tasks. Please check your Esri ArcGIS Compatibility workspace parameter, found in Navigator -> Workspace Parameters -> Translation. This 64-bit version of FME requires ArcGIS Desktop along with 64-bit Background Geoprocessing; ArcGIS Pro;

Hi everyone,I’m working with DWG files in FME — reading them, attaching XREFs, and then writing back to DWG.I’m trying to attach an XREF to a specific layer (something other than Layer 0), but so far I haven’t had any success. I’ve tried setting both the fme_feature_type and autocad_layer attributes, but the XREF still ends up on Layer 0.It also seems that when using the DWG reader, FME always interprets XREFs as being on Layer 0, even when they’re on a different layer in the source DWG.Has anyone found a way to preserve or specify the layer assignment for XREFs when reading/writing DWG files in FME?Thanks in advance!

Below is a screenshot of my workspace that creates a new feature class (AttributeManager_6_Output). This feature class will be edited by end users in ArcGIS Pro. I need to bring that feature class back into the workspace and join it back to caputure those edits. My problem is that some of the attributes will be updated upstream as well. I need to capture those edits as well without overwriting the end user edits. How am I able to set the attribute conflict independently (some attributes from Left and some from Right) in the FeatureJoiner?  

Looking at the new Define Read Criteria By: Custom Query option in the FeatureReader in 2025.1I feel like there should be a warning against using Define Read Criteria with Esri Geodatabase format as it uses sql and bypasses specific SDE functionality. 

This seems like is should be so simple, but I can’t get it to work! I want to take a CSV file that has Feature Class Names, FieldPrefixs, and Feature types. For example:FeatureClass, Prefix, FeatureTypeRoads, Road, LineWildLandUrbanInterface, WUI, Polygon. This CSV file will be dynamic, meaning that the Feature Classes that will be summarized will change.I then have a SummaryPolygon Feature Class which defines the polygons on which to summarize. I want to iterate through the CSV file, summarize the data for each CSV record, and then add two fields with the prefixs (ie Road_Miles, Road_MilesPerAcre or WUI_Acres and WUI_PercentArea) to the SummaryPolygon. I thought the workspace runner would work well for this, but the Child workspace isn’t updating/showing the new fields that were created after each iteration. Meaning the schema isn’t dynamically updating with the two new fields on the next iteration. In my Reader, I have Workflow Options set

We have a polygon shapefile in which features overlap because the data is self-reported. During our analysis, we noticed that when a feature is 100% overlapped by another, it is not considered in the clip process with another dataset. However, we want all features—even those that are fully overlapped—to be taken into account when performing the clip. What configuration or procedure should we use to ensure this behavior?

Hello everyone,I’m currently facing a challenge with writing an IoT data stream directly to an ArcGIS Online (AGOL) hosted feature service using FME. While I’ve successfully configured the stream to write to a local SQLite database, I’ve been unable to achieve the same with AGOL.I’ve attempted to use the Esri ArcGIS Feature Service Writer transformer, but unfortunately, it hasn’t worked as expected in stream mode. I’m wondering if there’s an alternative transformer or method that supports continuous writing to an AGOL feature service.Here’s a brief overview of my FME workspace setup:Input Source: Reading data from an MQTT broker in stream mode using the MQTTConnector. Data Processing: Filtering incoming messages into different groups based on sensor types. Output Goal: Writing the processed data to an AGOL hosted feature service. Runtime: The workspace is designed to run continuously to handle real-time data.An
