FME Flow

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

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.

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 proces

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,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 ou

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

Hello everyone,I have a question in regards to naming the filename of the datadownload output.I was wondering whether it's possible to change the name instead of having a name such as FME_55460769_1764252272631_14296.zip for example.I found a post with a workaround, but he post is already 7 years old and I don't manage to use the workaround succesfully. Does anyone know if there is a different and easier way to change the name of the zip file?

Hi, I am using an FME Server app in which a theHTTPCaller is used to call on a second FME Server workspace. Here are some of the tags used in the URL (opt_showresult=true&opt_servicemode=sync&opt_responseformat=json)Long translations fail and return a HTTP 504 (HTTP/1.1 504 Gateway Time-out) even with the connection timeout lenght and transfer timeout lenght set to 0 Is there a way to avoid these timeouts? I suspect that it has to do with the FME Cloud settings, anybody can shed some light on the subject? Cheers,Itay

Is it possible to turn off log entries like these?Workspace was last saved in FME version: FME 2025.1.3.1 (20251021 - Build 25645 - WIN64) Failed to free sufficient memory to reach the process usage limit. To improve stability and performance please increase the memory available to FME. Available memory can be increased by adding physical RAM, increasing swap space, or closing other applicationsThese just add clutter to the job reviewing process.   

Hello everyone,I am trying to create a FME Flow workspace which can be triggered via webhook and want to pass the result back to the initiating application for the user to download. The plan is more or less like this: In a webmap application, the user can create a bounding box. In the background the FME Flow workspace is triggered which then sends some HTTP-Requests to an OGC API, gets an xml response and parses that response into a more user friendly GeoPackage. That GeoPackage is then provided to the user via download.  Now that process already works partway. I managed to trigger the workspace via webhook and create the GeoPackage according to the parameters provided in the webhook message/body but I am struggling on how to now pass on the created file to the user/back to the webmap.The data is created within the shared_resources folders where I can access it but I cant seem to find any way akin to the data download or data streamin

I'm attempting to use PointCloudSurfaceBuilder in FME 2024 to build surfaces from a classified LAS point cloud (3D, ~3.6 million points, CSRS.UTM-11N), as part of a workflow to generate pit-free canopy height model (CHM) slices.My goal is to use the Search Radius parameter to control triangle edge length and prevent long connections across canopy gaps. However, I’m consistently running into the following issues:  Surface output is sparse or almost empty, even when using the full unfiltered point cloud (no slicing or thinning). Changing Search Radius from 0.45 to 1.5 to 10 meters does not resolve the issue — only a few tiny triangles are ever generated. Processing time exceeds 30 minutes per

I’m working with FME Flow 2025 and I’ve built a Flow App that allows users to run a workspace by clicking a “Run” button.My concern is about system overload: if a user (maliciously or accidentally) clicks the “Run” button hundreds or thousands of times, this could flood the job queue and potentially saturate the single engine I have available.I’ve looked into Job Queues and Job Routing Rules, but they only let me set priorities and routing conditions (repository). I understand that jobs can be routed to different engines using queues, but that’s not my goal. My goal is to limit the number of jobs submitted by users, not to distribute them across multiple engines.What I’m trying to achieve is: Prevent users from creating an infinite queue of jobs. Ideally, enforce a limit per user (e.g., max 5 jobs active or queued). Any ideas?

Hello.  We have several Flow Workspace Apps that use a customized browser icon and heading logo image.  I was wondering if those files can be retrieve from Flow or can be found in a folder path on the machine where Flow is installed, since we have misplaced those image files.  Any help would be appreciated.  Thanks.

Hello FME Community,I’ve encountered an issue in FME Flow and would appreciate your input.We have an automation webhook that receives messages from another system and then triggers a workspace. The source system is a building management system used by our real estate department. It sends a message whenever a new building is added or an existing building is updated, and this works perfectly.However, the problem occurs when a building is deleted. The delete message contains data only in the header and nothing in the body. As a result, FME Flow returns a 400 Bad Request error with the following output: {"message": "JSON Parse Error: Unable to read message body"}.The error goes away if I add {} in the body in Postman and then send the message to Flow.I’ve spoken with the administrator of the building management system about the possibility of including {} in the body, but unfortunately, that’s not an option. Question:

I was following this article where i tried to create a WMS service. Everything works as expected in FME form. Using the OGC WMS (Web Map Service) reader i am able to trigger both workspaces and get the result as expected , in my fme server jobs i also see that 2 GetCapabilities.fmw workspaces are ran and 1 getPNG.fmw workspace. I tried importing the same WMS url into ArcGIS Online but i see that only the GetCapabilities.fmw workspace is ran and not the getPNG.fmw workspace. Does anyone have some idea over why the getPNG.fmw workspace is not triggerd by the ArcGIS Online client? Thanks in advance,Keller.

Hi,I’m using the FME Server API to perform an audit and cleanup. I can use the API to retrieve lists of users, workspaces, and workbenches. Separately, I can also get a list of connections.I want to check if any of these connections are now redundant after the recent cleanup. Is there a way to link connection names to the workbenches they are used in, so I can identify and remove unused connections?I can’t see a way to do this via the API. The only approach I can think of is to download all the .fmw files and then read them in FME Desktop using the .fmw reader.Any help or alternative suggestions would be appreciated, ideally all within the api.Thanks!!

Hello all, I have a FME flow web-app (image 1).

 Hello All,  I have successfully created a Workspace App that allows the user to search for available sampling sites in our database, and return the matched results in a new webpage using the Data Streaming service. We are using version 2024.1 for both Flow and Form.The screenshot below shows the simple flow - the users parameter values are tested to see which are blank/missing for when optional fields have no selections entered/chosen. The appropriate SQLExecutor then outputs the matches to the HTMLReportGenerator which creates a HTML table for the writer to generate the content.  My end goal is similar to this question but differs

We have a job running as a stream, it is not using any specific stream transformers, but it calls an API endpoint and just runs over and over (~10s) as fast as it can poll the API and write the data. The problem is the engine does not release memory between runs, so it slowly grows and grows. And if left for weeks unchecked the server starts having low memory issues. We can stop and start the stream and it will release the memory back.  There is the server config setting MAX_TRANSACTION_RESULT_SUCCESSES which we have set to the default 100, but this does not seem to restart the engine and release the memory. Not sure if a stream just counts as 1 success so it never gets to 100 or what. So, wanted to reach out for any possible solutions for this? Only idea we have is to make and schedule a job that can call the v4 API to stop and start the stream every night. Any better ideas? Maybe some configuration we are missing? Thanks a l

Hello everyone,I’m wondering if we could rack your brains for some help. Where I work we had FME Flow and Form introduced in a rush for a particular project. In my team (GIS) we have some prior experience with FME Form but none with Flow. We have undertaken the online training but it’s no replacement for hands on experience.We fumbled through and managed to get the solution for the rush project sorted. However, I think our solution is a workaround as we had to make 2 flows, one to read from a database, do some stuff and then write to the FME Flow resources folder, and then the second to read from resources and write to our network share. We were never able to read from the database location and write to the network share in one flow, which seems wrong to me.We have moved onto other projects recently and are coming across the same problem (also in the backup scheduler). From poking around a bit more we’ve found that if you run the workspace locally in Form > g

Hello everyone,I hope you are doing well.I encountered an issue when trying to polygonize text in DWG data that contains Japanese characters using the Transformer: TextStroker. The text was displayed as tofu (blank squares).When I tested the same process on FME Form 2025.1.1 (Windows 11), the text was polygonized correctly without any problem.If anyone has insight into possible misconfigurations or additional steps needed for proper handling on Linux, I would greatly appreciate your advice.Environment: OS: Linux Ubuntu FME Flow: 2025.1.1 Target language: Japanese Desired font: Noto Sans CJK JP Notes:Font recognition status on OS:>(base) ubuntu:/usr/share/fonts/opentype/$ fc-list>/usr/share/fonts/opentype/noto/NotoSansCJK-Regular.ttc: Noto Sans CJK JP:style=Regular>/us

Goodmorning!  I have an FME Flow workspace app, and it won't run. It has worked for about a week, and after that it stopped working. The problem is, according to the logs, the AttributeFileWriter. It just says, rejected, nothing more. We believe its the string we use to dynamically choose the output location of the photo's. See attached picture. This is the string: $(FME_SHAREDRESOURCE_DATA)/@Value(Jaar)\@Value(IncidentNummer) @Value(Dag)-@Value(Maand)-@Value(Jaar) @Value(Plaatsnaam)\@Value(IncidentBijlageId).jpgThe strings works just fine in FME Form, but, not anymore on FME Flow. This string has worked before on Flow, but stopped working for some reason. We did look into it, but could not find a solution to this. Can anyone explain this? Thank you!
