Hello,I try to do something very simple but I think I must be dumb. So I’m working with a ArcGIS Featureservices data which are agriculture data. In the RPG_2023, the attributes associated to “CODE_GROUP” will be only numbers like 11,16,18 so very simple.In the user parameter I try to add the “CHOICE” parameter because I want the script to ask me which kind of attribute I want to work with.I try to use the import wizard using the valuesBut then in this box is going endless ==>I don’t know if I do something wrong or it’s normal for the reading dataset to be so long.I don’t have a lot of different attributes (maybe 26 max different kind of “CODE_GROUP”). If someone could help me because I don’t understand what do I do wrong. Or if you have documentation about the subject I will be very happy to learn more about it.Thanks a lot and sorry for my english !! 

Hi all, we are on Flow 2025.2 and we use Geometry Parameter for quite a few ws apps. Now we are living with the bug FMEFLOW-26285Changes to the default basemap of a geometry user parameter under the Parameter Defaults when creating/editing a Workspace app do not get applied to the Workspace app. Users accessing the workspace app will see that the default basemap is unchanged. Any tips for a workaround? Can one change the default using javascript in the webpage possibly?

Hi, I am a software developer, but don’t know much about FME yet. Please forgive my ignorance :-)I was asked to create a simple wrapper around the REST API v4 that lets a user start a job, and download the results as a zip file.Generating a token, submitting a job, and getting the job’s status is fairly straightforward, but I am at a loss when it comes to downloading the results. I see that there is another API /fmedatadownload, but it seems that the token I use when submitting the job does not work here. I tried passing it in the Authorization header, as a query parameter, and I also tried Basic authentication, but all of these return HTTP 401I am sure this must be very simple, but I am probably overlooking the obvious here.

Hey all, After updating my FME Form to version 2025.2.2 & updating the ArcGISConnector package one of my FME Flows has stopped operating in the same way. I have an ArcGISOnlineConnector Transformer which updates a hosted CSV item on an ESRI Enterprise system. This had been previously working well & updating each row within the CSV and the CSV on Enterprise showing as updated after the flow had completed. Following the update the Flow now only updates the First & Last feature according to the log. The CSV on the Enterprise does also not show as having been updated when the flow has completed. This worfklow does still work on FME Form. Previously FME Flow went through each feature on by one like the second setFME Flow:125 2026-4-17 08:52:50 | ArcGISOnlineConnector_2_CALLER (PythonFactory): Processed 1 of 16,927 features126 2026-4-17 08:52:51 | ArcGISOnlineConnector_2_CALLER (PythonFactory): Processed 16,927 of 16,927 features FME Form:ArcGISOnlineConnector: Updating file cont

I received a few old Soviet geological map scans to experiment with georeferencing. Can we place simple JPEGs where they belong in the world? It actually quite possible today with Gemini (other models, unfortunately, are not even close).The idea is simple - find the the map on the scan with a segmentation mask, clip the scan with the mask, make small crops of the map corners and ask AI to find pixel coordinates of the neatline corner and read the coordinates. The old Soviet map sheet nomenclature is quite elegant, and it’s easy to make names and calculate projection zone from scale, latitudes and longitudes in the map corners, so I was able to build control vectors to transform the pixel coordinates into Gauss-Krüger. Of course it only makes sense with automation on multiple maps - drop your files in a folder, let FME do the work while you enjoy your coffee 😎Now I am exploring whether I can replace Gemini with other models, especially local ones such as Gemma 4. So far, the results ar

I’m working on building a workflow in FME (2025.1) to publish and maintain a hosted feature layer in ArcGIS Portal/Enterprise, and I’m running into issues getting upsert (insert/update) functionality working properly.GoalI have a point layer that I’m creating in FME and writing to a hosted feature service that I created FROM FME. I want to:Run the workspace repeatedly Update existing features if they already exist Insert new ones if they don’t Avoid creating duplicates each runI keep running into problems with global ID or object ID. I’ve tried using the Unique Identifier Generator to create a Global ID.

I have been following this article https://support.safe.com/hc/en-us/articles/25407494166029-Connecting-to-Salesforce-in-FME but am getting this error “Request to update access token in connection storage failed. (HTTP Error 'HTTP/1.1 400 Bad Request': '{"error":"invalid_grant","error_description":"invalid code verifier"}')” when I test the connection

Hi,I use a JSONTemplater to make a geojson with nested attributes. It works fine. The only thing I notice is that I have a number in real32 (1.21) and when it comes out of the JSONTemplater it has the value 1.2100000381469727. The extra decimals apear out of nowhere. How can I change these back to the original? Or can I use some kind of casting? I use FME 2023.2.5.Thank you

Can the dynamic parameters in FME Flow Apps, as described here:Dynamic Parameter Configurations in FME Flow Apps – FME Support Centerbe made to cascade, i.e. so the value chosen in one parameter affects the choices available in another?How does one structure the JSON to do this?

If an automation is triggered by a schedule, you can obtain the schedule properties via the Schedules list.  https://docs.safe.com/fme/html/FME_REST/apidoc/v3/index.html#!/schedules/list If an automation is triggered by a topic, how do you obtain the name(s) of the topic(s) that trigger that automation?If an automation posts to a topic, how do you obtain the name(s) of the topic(s) that automation posts to?

I developed a small MCP server that exposes an FME workbench (.fmw) as a service that can be invoked via natural language, using an AI client (e.g., Claude).The interesting aspect is the architecture and the simplicity of "assembling" the various components:1) I build the FME flow that executes the workflow, managing logic, transformations, and formats (we leave to FME what belongs to FME),2) the MCP server exposes operations and parameters in a controlled manner,3) the AI ​​client interprets the request in natural language and translates it into a structured call. 

Hi all,I have a fault tolerant deployment of FME Flow 2026.1 in our private AWS account. Our security team requires us to limit the number of ports to be opened between WebUI/Core and Engine hosts (eg. least privilege).Is there a best practice rule/formula in calculating the number of ports required to be opened depending on the number of engines per host and the number of hosts in your deployment and the starting port number? ThanksExample:3 engines / host and 2 hosts = 6 enginesIs there a redundant factor that needs to be applied? eg. 2 timesTherefore 3 engines x 2 hosts x 2 redundant factor = 12 TCP ports are required.The starting port number should be from 50000 fmeFlowConfig.txtFME_SERVER_PORT_POOL=50000-50011

Hi all,I've been using the FME Flow REST API v3 for server metadata extraction and analysis, and one of the key endpoints I relied on was the datasets endpoint to extract reader/writer information from workspaces:GET $(Environment_URL)/fmerest/v3/repositories/{repository}/items/{item}/datasets/sourceGET $(Environment_URL)/fmerest/v3/repositories/{repository}/items/{item}/datasets/destinationThis gave me a clean, simple output showing the format, location, and name of each reader/writer, exactly what I needed for server analysis and metadata:With the v4 migration I can see this has been explicitly removed with no direct replacement:Description V3 Endpoint Suggested Action Get dataset information for a repository item /repositories/{repository}/items/{item}/datasets/* This functionality has been removed. I've looked at reading the .fmw file directly using the FME Workspace Reader as an alternative, but the data is incomplete and doesn't come out in a clean usable format the way

Hi there,I have installed FME Flow 2026.1 in AWS has a High Availability WebUI/Core with distributed engines.The setup uses HTTPS on an internal url (corporate network)When I try to connect FME Form to Flow, I get the following error message Unable to retrieve public key from FlowUnable to establish secure communications with FlowDeployment parameter access failed (Connection Error) - Unable to connect to FME Flow. Has anybody seen this before? ThanksWhen I use the url in the browser on the same machine (tested on 2 different machines), i can log in using my admin user account 

I have several automated jobs that use either a startup or shutdown python script.  These scripts run fine in workbench and even in the ESRI Python interpreter on the Flow machine.  The issue arises when I run them from Flow.  When it gets to the script it will output expected products until the exportToPDF command at which point it fails.  No errors are indicated anywhere except in the Engine Log where this is displayed: WARN     localhost_Engine2   393562 : Process "localhost_Engine2" ended unexpectedly.

Hi thereCan anyone offer guidance on how to remove three stray vertices which remain after using the Dissolver transformer, please?Many thanks.
