Deployment

Hi there,I have installed FME Flow 2026.1 and have used the HTTPS option with a pfx certificate from the installer wizard on Windows Server 2022 AWS EC2.I can open the WebUI with https:// and everything looks fine and log in with SSO/SAML. The ‘Services’ page has the urls as https:// as well. Question: Is the steps in ‘Configuring for HTTPS’ still required?

Hello community,for a few days, I have been struggling with our FME Flow. It occasionally throwsand I am the admin, I asked myself and… crickets.The only change we did recently is a Python library install.FME Flow gets in this error communicating state and then recovers. We tried restarting FME Flow, it likely made some difference (I am not sure whether it indeed fixed the problem even for a short period of time as FME Flow works between these messages anyway), but it didn’t last.This is FME Flow 2024.0 build 24612.Any ideas will be much appreciated.Thank you :)

I have installed FME Core on windows machine and distributed engine on Linux machine. I am getting following error in my logs “ERROR : FME Engine failed to register with FME Flow 'FME-CORE-DEV' on port 7070. Failed to verify message authenticity” Engine appears on FME FLOW but it is not active and always appers as disconnected.

I utilise Deployment Parameters to sde database connections. When upgrading to 26.1 and then starting to test, deployment parameters failed due to being missing. I moved the shared resource path between versions, so I guess this is to be expected2026-4-21 16:25:07 | An error occurred while attempting to retrieve the connection parameters from the connection file 'D:/FMEFlowShare/resources/system//_RTIOSDE_TEST_DEVDATA_FME_Flow.sde'Deployment parameters, specially SDE file connections….are not restored from application backup, when you change the Flow Shared Resources from the C:\ProgramData\Safe Softwareto a D:\FMEFlowShare 

Hi,I need to make the Esri Arcgis connector available for all users within a APP-V packages, however these connectors install under the app data folder. Is there any way to install these connectors on a program files or data folder so that all the users can make usage of the Hub connectors. Is there a way to change this path? Thanks in advance. I already tried to copy the files to the program data however FME doesn't see the files and is unable to access the connectors. Yours sincerely.  

Hey everyone! I wanted to share something I’ve been working on for a while.When I’m debugging our own FME Flow, or one from a supported user, I often need to dig into the log files to track down errors or evidence of what went wrong. This can be really time-consuming: there are many files to open, and some of them are very large. Most of the time I end up just jumping between files and scrolling to the right timestamp, instead of actually focusing on what happened. To make this easier, I built an FME workspace called FMEFlowLogInvestigator.This workspace can be published on FME Flow with the Data Streaming Service. It takes four user parameters:

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?

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): Processe

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

Has anyone else run into issues with how things are displayed in FME Flow 2025.2.1 Examples: Engine Assignment Rules - we have two hosts which differ in name by suffix only. The way engines are displayed on the Engine Assignment Rules tab means you can’t quickly tell which engines are assigned as the critical bit is displayed as … (the full names are available on mouseover) The hostnames displayed in No proxy also have their urls partially replaced with …. so there appears to be no way to actually check via the user interface what values are entered here. In 2024.1 these values were displayed in full 

Hi all!In our 2025.2 Flow installation we have AD synchronization and authentication for quite sometime, with some 100+ users and a number of groups. Now we are about to deploy SAML - I am able to get it to work for a new user/role, but if there is an existing user/role there is a collision, and the process fails.Am I understanding it correctly that I actually have to delete (or at least rename) all users and roles before we can start using SAML fully?What we see in the logs:417551 : An error occurred during SAML login: Specified user role already exists.417551 : An error occurred during SAML login: Non SAML user account "nordpil" already exists. Please contact system administrator for support. 

Hello,I have a workspace with a custom transformer that does lot’s of things but we can consider this :Get a list of feature type to read Read data with a feature writer Make a bunch of tests with spatial relators, feature merge and plenty of transformers If some error are found : those objects are outputed If no error are found, nothing is outputed.In local, with FME Form, no problem, it works, nothing is returned :REGLE_TOPOLOGIE KO_PONCTUEL_TOUCHES_LINEAIRE Output Renamer/Nuker (TeeFactory): Cloned 0 input feature(s) into 0 output feature(s)REGLE_TOPOLOGIE KO_PONCTUEL_INTERSECTS_PONCTUEL Output Renamer/Nuker (TeeFactory): Cloned 0 input feature(s) into 0 output feature(s)REGLE_TOPOLOGIE KO_LINEAIRE_INTERSECTS_LINEAIRE Output Renamer/Nuker (TeeFactory): Cloned 0 input feature(s) into 0 output feature(s)REGLE_TOPOLOGIE KO_LINEAIRE_CROSSES_LINEAIRE Output Renamer/Nuker (TeeFactory):

HelloWe have just updated FME Flow to 2025.2.4.

Hi Community,I tried to use a DB Connection as Deployment Parameter and set it as Default value in the User Parameters in Workbench as shown in Screenshot below. However when I publish this workspace to Flow the User Parameter with DB Connection is empty and I need to select again the DB Connection manually (2nd Screenshot).Is this an expected behaviour? In my logic the User Parameter should be set automatically (works like this e.g. for Text Deployment Parameters as User Parameter). A workaround I found was to delete the User Parameter before deployment then the Job in Flow uses directly the correct DB Connection.Thanks for your response in advance - BR Kai. Deployment / User Parameter Settings in Workbench

Is there any way to cancel a system restore, it appears to be hung at  Unzipping migration package stage for 1.5 hours now.  I think the file system/network glitched during the process.  There is no cancel in the UI, no jobs running.  

Hi there,Just finished a fresh install of FME Flow 2025.2.1.I was configuring the backups and noticed that the output files were not getting a timestamp.Looking at the httpcallers they both submit using the non-timestamped attribute:If Append Date is No:If Append Date is yes:What it should be: Thanks,Marc

Is it possible to turn off the “Browse Resources” button or make browse file system larger in FME Flow apps? Here is a screenshot of what i’m referring to.   

Dear Community,i am experiencing a strange behavior from our FME Server when uploading/publishing a FME Desktop workspace in FME Server.Previously, it was possible to publish workspaces from FME Desktop to FME Server.Recently, publishing from FME Desktop is no longer possible, nor is it possible to upload workspaces to FME Server via the Web UI.I only receive very little information about the error in FME Desktop ,also with the debug logging.The following excerpt from the log:Successfully retrieved service properties.Retrieving service parameters for ‘geodatabase_sde2none.fmw’...No service parameters found.Uploading as ‘geodatabase_sde2none.fmw’...Publish failed - FME Flow encountered an error.When I upload a workspace in FME Server via Web UI, I get the following messages in the network console of the Browser:Get Call <FME-Server-URL>/repositories/{repository}/items/{item}returns a 404

Hi!I have had trouble fully understanding how to setup the ArcGIS Server license on the FME Flow VM. I cannot seem to find clear documentation online to walk admins through this process. I understand that an ArcGIS Server license needs to be on the same machine as FME Flow if workflows contain ArcSDE and gdbs.If possible, can someone please provide steps, or link to an article that clearly walks through this setup? For some background, my organization has an Esri Enterprise environment, but I have no idea if when walking through the setup if a new site needs to be created, or if I’m supposed to join our existing site, or if joining an existing site could disrupt our Enterprise environment if things arent setup correctly on on FME Flow machine.Any and all help is greatly appreciated!

Is there documentation on where the various logs for FME server live? And also something for how they are structured? I’d like to create a datadog/grafana esque dashboard to be able to view these easier.  Thanks!

We just upgraded to FME Flow 2025.2.1 and are now seeing some odd errors in our nightly data automation. Two nights in a row we have had jobs stopping at the same spot, there is nothing in the job log, and the job just fails with the message Job did not complete. When I look in the Windows event log (SYSTEM) for the server I can see a note of a “Fail Fast Exception” in fmeengine.exe - has anyone else seen anything like that? 

Hi all,In our company we are using FME Flow, it's works great.Except with one workspace we get some errors. On the desktop version is works flawlessly! The error we get is about a plugin (STUF-GEO) that cannot be loaded:144 2024-7-3 21:48:01 | File C:\Program Files\FMEFlow\Server\fme\metafile\STUF-GEO.fmf could not be opened 148 2024-7-3 21:48:01 | Could not load module 'C:\Program Files\FMEFlow\Server\fme\plugins/STUF-GEO.dll' : 'The specified module could not be found' 149 2024-7-3 21:48:01 | Could not load module 'C:\Program Files\FMEFlow\Server\fme\STUF-GEO.dll' : 'The specified module could not be found' 150 2024-7-3 21:48:01 | This FME edition does not recognize the `STUF-GEO' reader.

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?

I upgrade FME Flow from 2024.2 to 2025.2.1 using the Windows express installation method. With all setting using default.Under “Engine Management” the localhost showing have 0 standard engines. Even I manually change it to 2, it stays at 0. FME Flow Engines service is running correctly. When I tried restart the service, FMEEngine.exe will show on details tab in Task Manager then disappear. When I tried run FMEEngine.exe, this error pop up:processMonitorConfigEngines.txt:NODE_ADMIN_PORT=7500NODE_MANAGED=true# ENGINE process configuration templateTEMPLATE_START_ENGINE="C:/Program Files/FMEFlow/Server/fme/FMEEngine.exe" REGISTER_FME_ENGINE localhost 7070 DEFAULT "C:/Program Files/FMEFlow/Server/fmeEngineConfig.txt" -ENGINE_HOST_NAME localhost TEMPLAT

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
