Fetching a parameter of a Custom Transformer in a PythonCaller (of that CT), results in error

Hi, It seems to me that there might be an issue when I'm trying to fetch a parameter value of a Custom Transformer, from a PythonCaller inside that Custom Transformer.  If I do so, I obtain an error. When I try to do so in the main workspace, or when I add the name of the CT in the parameterfetcher, I don't get an error, and it works. See below screenshot and the attached demo workspace for an example.This seems like a bug to me, but it would be nice if the community can have a look alongside me. Kind regards, Thijs Ps. as a sidenote, I came across this Community Question in which the best practice for accessing parameter values inside a PythonCaller is discussed. In it, it is mentioned that best practice is to use param = fme.macroValues[‘parameterName’] in favour of param = FME_MacroValues[‘parameterName’] Additionally, it is mentioned that DaveatSafe created a problem report 4 years ago to make sure that this best practice is also honoured in the script editor for the Python

TIN Not Creating Correctly

Hi,I’m having a issue making a TIN properly in FME. Basically FME is interpolating points/vertexes that don’t actually exist in the original data. What I want to do is make a TIN that considers only the vertexes of the features I give to it (point/lines and breaklines). I do not want FME to make up data that does not exist.Does anyone know a way that I can do this?For example in this example this is one break line. It should only have two TIN vertices (the ends). No triangles should be created from any interpolated points However, when I look at the TIN for the same spot it has created 6 vertices I am using FME workbench/form 2023. I’ve been trying different settings for the SurfaceModeller and the TIN generator

Dynamically setting "Columns" on UPSERT in FeatureWriter to PostgreSQL

Hi, I have a dynamic workspace where I am reading in multiple csv update files for multiple feature types to upsert into our database. I had set the primary key dynamically dependent on the target table in the database. I cannot set a where clause on an UPSERT (which I do use with other feature types that have the ability to do I, U, or D) so went to use the "Row Selection: Columns:" section instead. This parameter does not work in the normal way with attributes. It presumes the selected attribute is the primary key field (no orange left arrow in front of the name), rather than using the value. I tried manually adding @Value(primary_key) (the attribute that stores the primary key column name) in the parameter but the feature writer also presumes it is literal and obviously can't find a column called "@Value(primary_key)" and errors. This is something that I would like to do, and is very much a part of a dynamic workflow. Otherwise I will have to create one dynam

iOS18 and HEIC files - are they supported in any version of FME?

It seems that in the iOS18 update Apple made changes to the HEIC file container that means the FME Feature Reader using HEIF (High Efficiency Image File Format) now fails to read the HEIC files.We are currently using FME 2022.2.Is there a later update that will support iOS18 images? Is there an alternative way to read in these images successfully?

Can FME Write ArcGIS Enterprise Attachments

Hi Everyone, Looking for some assistance, I’m using FME 2023.1.0.0 trying to migrate some existing Survey-123 forms and data with attachments from ArcGIS On-Line to our new Enterprise portal.Our survey-123 form has a singular photos field for tracking a picture of the bus stop, it also has a repeatable photo’s field (table) where the inspector is able to take and attach multiple deficiency photos to the stop if one exists.  In FME, I’m able to read in the AGOL feature service that hosts all of the survey information, I’m also able to write out the tabular information from the point layer to the new Enterprise feature layer that was created when I saved the Survey-123 form in Enterprise.The part that I’m currently struggling with is getting the singular photos to attach when writing the tabular information out to the Enterprise feature service so when I view the points in ArcGIS Pro, they appear in the attachments tab of the attributes editor like they currently do with my AGOL service.

PDFs with AI

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!

Changing a cell entry in an overly complex Excel document

Hello yet again.This time I am experimenting with a complex Microsoft Excel document, its basically a calculation file that contains quite a lot of sheets, macros, references and formulas. Idea is that instead of sharing the excel document with the people that need to use it that I would just host it on our Flow, people would then have an option to fill out some published parameters in a flow app and then get a single excel sheet returned with their results (cutting out all the underlying datasheets and formulas and macros etc).Or to sum it up: I have a complex excel with formulas, read that excel in FME, change values in cells in FME, write out an excel from FME that would then recalibrate/recalculate based on those changed values.So I have figured out how to single out cells in the excel table where (basically using counter, and tester for that single number, link to attribute manager where the new value can be inserted to replace the old one, back to a FeatureMerger to put the new v

Setting default values for attribtues

NullAttributeMapper, AttributeCreator or otherWhat do people use to set default values for attributes?In the case that I have is a json document - in the case values are missing I need to set a default value. Ideally I’d use an NullAttributeMapper, however, there are upwards of 10 values I need to set and I don’t want to use 10 of these. The other option I see is an AttributeCreator/Manager with conditional values which is what I would normally do.

Managing Reading Order Conflicts

After adding FeatureReader_2, the reading order started prioritizing the XML block. Then, a join occurs with the Data Dictionary block, but since the XML is fully read first, when the flow reaches the FeatureJoiner, the data dictionary has not yet been processed, causing an error.This started after I added FeatureReader_2, because I need it to read shapefile files to extract the name and coordinate system, which are parameters defined in my spreadsheet with the paths to each shapefile.Is there any way to make the XML and Data Dictionary blocks read simultaneously? Or, since the FeatureReader is a reader, will it always have priority?

How to get Raster palette index value out from WMS

I’m working with getting raster imagery in the area of interest out from the WMS. It’s the Land Coverage WMS. (https://dmsdata.cr.usgs.gov/geoserver/mrlc_Land-Cover-Native_conus_year_data/wms?)End goal is to clip the Raster out from WMS into smaller area, and I need to be able to write attribute table showing the value number & RGB value in the Raster.End Product. (Smaller Raster with attribute table)​​​​​​The issue I’m having is that the Palette index seeing inside ArcPro and FME is different. (Approximate location, SE corner of Possom Kingdom Lake, Graford, Texas, USA.) (32.856463, -98.431004)Screenshot from ArcPro. When clicking Blue (Water) the value is 11. Screenshot from FME. When viewing the Palette after using RasterPaletteExtractor it showed Blue as 0. and I cannot figure out how to get the value “11” out of it. Also If anyone can help me figure out how to write the raster file out with attribute table that would be greatly appreciated. I’m quite new with Raster, so I’m no

Introducing BetterReportGenerator (BRG) – a fresh, modular take on HTML reporting

Hi everyone!Today I’d like to share a new approach to building reports in FME, along with an entire family of custom transformers I’ve created to support it. Why I built BRGI’m a long-time fan of the HTMLReportGenerator. It lets me craft reports quickly, and I love the versatility of HTML compared with, say, PDF. I even demo it in every Intro to FME course as a great example of “let FME handle the code.”But as much as I love it, I’ve always hit three pain points:1. Plain styling – it could really use a dash of CSS/Bootstrap.2. Hard-coded content types – adding a new chart or HTML element isn’t trivial.3. Cumbersome feature ordering – managing Sorters and AttributeCreators just to control layout can get messy.Earlier this year I had to build a highly procedural report with lots of HTMLLayouters, AttributeCreators, and Sorters, and the workspace quickly turned into spaghetti. That’s when I thought: I already improved SystemCaller with BetterSystemCaller… why not do the same for report ge

Esri Geodatabase Writer: Feature Type Definition ... was requested, but not defined

In the stand-alone FME Form my FME script works well. However, using the same script in ArcGIS Pro faced error saying Esri Geodatabase Writer: Feature Type Definition … was requested, but not defined. A possible reason is that you may not have permission to create the Geodatabase. The error number from ArcObjects is: '-2147467259'. The error message from ArcObjects is: {}FeatureWriter or classical Writer, there is no difference. With other FME scripts (created by others) a fgdb can be created. Why not the mine?

How to categorise geometry changes between parcel layers

Hi there,I have 2 parcel datasets, a master copy and a weekly update copy that I need to process into the master copy. Each parcel only appears once in each dataset and has a unique parcel ID so matching is fairly easy. I’ve used a change detector to flag any parcels with geometry updates, but now I need to identify the type of change that has taken place. This could involve parcels being split, merged or just the boundary being updated. What is the best way to do this? The logic in my head is this so far:Split parcels - Either, mutliple new parcels being inserted within the boundary of one that has been deleted OR Parcel boundaries shrinking and new parcels being added within boundary of originalMerged parcels - New parcel being inserted that takes the place of multiple deleted parcels OR Parcel boundaries growing to cover extent of deleted parcels

Open Telemetry and Visualization for FME Health - Grafana Stack for Example

I would like to hear about everyone’s experience with “Observability” of “FME Flow” in understanding it’s health and operational usage (for example, including FME Flow in a “trace” or understanding/correlating logs in relation to metrics)My context, I’m working on maturing our GIS stack to a completely new level. Modern Observability is a major objective for us.Now, I’m working on a design and architecture where our observability platform will be able to tell us about an operation “end to end” with traces, give a high level view of failed jobs/automations/etc at a high level BUT allow us to view errors in jobs AND the system at a high level in order to know when users may be experiencing issues early on.Mainly, we want observability that will help us see wherever our users start having issues and make “incident” management a little easier for diagnostic stages.NOTE: I’m looking at the Grafana LGTM Stack as an option for us but I’d really like to hear about any experience/solutions with

HTTPCaller truncating edit request with ESRI's REST API

I’m using an HTTPCaller to applyEdits using ESRI’s REST API. It includes sending along some JSON to add to a table in a feature service. The workspace runs successfully testing with 1 or 2 records in the JSON parameter, which is all sent with a single HTTP call, but fails when testing with 10 records. It looks like FME is truncating the HTTP string, which causes the request to fail. That’s what it looks like in the FME log anyway; the query string appears on two lines (see attached screenshot). If I try applyEdits in a web browser at the REST endpoint and paste the JSON in manually, I can add the data without issue. Is there a parameter or formatting change I need to make to keep FME from truncating the HTTP call? (FME Desktop/Form 2023.2.2.0, build 23764)
