Flow Hosted

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

Hi everyone,I’m seeing a reproducible crash in FME Server when using the ili2fme Writer.Environment: FME Flow 2024.2.3 (Windows Server) also happening with FME Flow 2025.2. ArcGIS Server 11.4 on the same machine Nightly scheduled jobs (~50) using ili2fme Writer to validate and export INTERLIS data Problem: A job that fails with model validation errors finishes correctly.

Is it possible to use FME Flow Hosted with a Remote engine located on an internal network. Thinking that this configuration would minimise FME Flow core maintenance, Simplify firewall rules, provide access to internal network resources like file system shares and databases... If it is possible, is there any documentation on how to setup this configuration.Cheers,e. 

Hi All,We have FME Flow (and Hosted) 2023.2.I would like to set up a FME Flow Hosted instance. The instance will have engines configured both on Cloud and on-premise. I am not very sure if the FME Flow Hosted instance can connect to the remote on-premise engines through so-called remote engine service. I read a discussion of the topic in this Forum below. It appears to be negative. But the discussion was 9 months ago. Not sure if it is still valid today. As the FME Administrator's Guide states, “Customers of FME Flow Hosted can also connect to Remote Engine Services.” https://d

Hello!I need to create an automation that will calculate 3 condition scores based on a series of questions answered via S123 submissions. What transformers would be best to use to calculate the condition scores? I’ve tried using the expressionevaluator, but it seems like the values don’t all get transferred. I’m also having a difficult time writing the calculated scores back to the feature service, what parameters should be set when writing calculated scores back to the feature service?Thanks for any help! 

Hi I am running a flow in FME form to send some automatic email and it is working fine. However, when I publish this to FME flow, it throws an error message below:I see in some of previous post to delete safe.emailer under reources and package. I did try that, however issue still persist. Can anyone please help? 69 2025-10-15 19:46:41 | PythonFactory failed to load python symbol `fmepy_emailer.Emailer' 70 2025-10-15 19:46:41 | Factory proxy not initialized 71 2025-10-15 19:46:41 | Emailer_CALLER (PythonFactory): PythonFactory failed to process feature

Does anyone know how to create an app to allow external users to upload ANY TYPE of data to a specific place :) ?Can be on flow or on our computer :)I can only find solutions for data of certain type or to be an input into an pre existing file.

Hi,We want to install FME Flow Hosted and would like to access to our internal network, so users can Read and Write files from the several disks.How can we do that?Thanks!

I have a scheduled automation which runs every hour, it just checks how long the job queue is - the are no user parameters.Once a month or so I get an ERROR in the workspace.The error is (log attached):2025-07-10 09:58:00| 0.0| 0.0|ERROR |'\xA0\xC2y\xDD/Z\x00\x0010 09:58' is not recognized as a valid encoding name.It’s an old workspace written with FME 2020 that’s been migrated a few times in FME Server to in FME 2024.2.2The log indicates that something is getting garbled. I can see part of a timestamp in there - the timestamp is the the start time of the job. I’ve see a similar error in other jobs as well on customer servers as well with different jobs (also intermittent. Has anyone else experienced intermittent errors like this?I have a hunch that making a whole new workspace in FME 2024 will make the error go away - but was curious is anyone else had run into this

We have an FME Flow Hosted instance running and I need to connect to an MS SQL Server. I have seen from the Reader/Writer documentation that MS SQL is not supported from FME Flow Hosted.Does anyone have a suggestion how we could still connect to MS SQL?The question is very relevant to us, since we plan to migrate to an FME Flow that will also run from an Linux-instance, which seems to be the cause why it isn’t possible to connect to MS SQL. N.B. Our current FME version is 2024.0.3.

In my FME Flow app - I have a geometry/location picker option and sometimes the map is not centered right/doesn’t load correctly (notworking.png) but once a user refreshes the app a few times it goes back to working again (working.png). I’m on version 2022.1 of Flow Hosted and have the screenshots of what the different maps look like below.  

Hi everybody, Has anyone had success with accessing a file share on a domain-joined server from an FME Flow instance hosted on a VM that is not domain-joined? If so, what mechanism did you use to put this in place? Thanks for any thoughts and ideas!

Hi,I’m attempting to run a workspace on FME Flow Hosted from within another workspace with an HTTPCaller using a webhook URL.The child workspace will eventually return a URL link to a zip file as it uses the DataDownload service.The workspace can take some time to run (> 5mins) as the data can be quite large.My issue is that I want to run the job synchronously so I’m able to retrieve the URL within the parent script to send it within an email, but the HTTPCaller always times out if the child script takes longer than 300s to run even if I set the timeout values to anything over 300s or even 0 (wait indefinitely). It is successful if the child script runs quickly (<300s).This is a problem as most instances will take longer than 300s.I don’t understand why it times out if it goes over 300s even if I tell it to wait longer.Is this a bug? If so, is there a work around or is it on the path to being fixed?Thanks

From FME Script I’m using FMEFlowNotifier and sending one attribute value to a specific topic. Then I have a subscription that listens on that topic. So far so good. The problem is that when email is sent, the email body that I specifified on the server is not included in the mail.  Anyone who can think of a reason for this?   

Hello, we noticed that with multiple scripts that have the feature portal service writer problems occurred:  This is part of the log file when trying to run the workbench script:Loaded Python module `arcgisonlinefeatures' from file `C:\Program Files\ArcGIS\Data Interoperability for ArcGIS Pro\python\fme-plugins-py311.zip\arcgisonlinefeatures\__init__.pyc' Writer `ARCGISPORTALFEATURES_2' of type `ARCGISPORTALFEATURES' using group definition keyword `ARCGISPORTALFEATURES_2_DEF' Loaded Python module `arcgisonlinefeatures' from file `C:\Program Files\ArcGIS\Data Interoperability for ArcGIS Pro\python\fme-plugins-py311.zip\arcgisonlinefeatures\__init__.pyc' Message Type: fme::internal::_v0::py::Exception Python Exception <ValueError>: invalid literal for int() with base 10: '<Unused>' ARCGISPORTALFEATURES writer: An error has occurred.

Hi all, I am wondering if anyone has faced a similar challenge. I created an FME workbench and published it to FME Flow successfully with some user parameters. The challenge is that I would like to send a message to the user after the job has completed running (or if failed). So instead of saying the job is completed or failed, I would like to modify it to give a more meaningful message.I do not want to send emails to users, otherwise I would have tried topics or automations. I just want to send a message (from an attribute) that appears at the end of the job.Thanks for the support in advance! Regards,Maadh

Hello FME community, here’s an outline of what I’m trying to accomplish:The fmw is included as a FME Server Workspace App (Server version 2021.2.5, Build 21816 - Linux). The fmw searches for features within a specified area (drawn by the user in the map) and if features intersect the drawn area, they are bundled into a FeatureWriter and provided to the user via a DataStreaming service. This works great when features are intersected.When features are not intersected, a NoFeaturesTester (stored in the same Repository as the fmw) directs the output to create a HTML file (FeatureWriter_3), created and stored in $(FME_SHAREDRESOURCE_TEMP). This file says something like “No results returned, the are no features of type X.Y,Z in the extent MinX, MaxX, MinY, MaxY...etc).Each time I test the App, the html file is created and populated correctly.

I have two questions about hosting on the FME Flow Hosted ServiceThe first is, when the Cloud Flow is offline, is it possible to show another page or change the standard offline page? I am trying to save some costs to run the Cloud instance for only certain hours, and it would be nice to give users feedback, which informs them of the times the service is live.The second is,how can I use my own domain for the Flow Cloud Hosting? I would like to change it for pure simplicity and because it avoids confusion to users who don't know what fme is. Is there simple ways to change these two things, any help would appreciated, or links on

Hi all,I have a workbench which has a parameter that asks for a .ZIP file for input.Specifying extension filters works in workbench - user can only add/view files with an extension “.ZIP”When i publish this to FME Flow, and create a flow app, the extension filters are ignored and the user can select/view any file of any type.Bug?Using FME 2023.2.0.0.FME Flow 2023.2, Build 23747 - win64thanks

Hi All,I am getting this error when i open FME Workbench and I am not sure what to do at this point this was working for me.

We have two hosts for a fme server application. One is working fine. But, another host app service was stopping frequently. getting above error for one of the host  

Hello,In FME flow, when I try to share an “automation” using the corresponding button, I get a blank box with the “OK” button greyed out and no ways to share the automation of other users of the fme flow instance.Did I missed something ?  Thanks for your feedback !

We have 2 job submitter services to validate the data they’re sent, write files to FME Server/Flow resource directory, write data to an Oracle database and send a response of the data validation and writing via an HTTPCaller.As far as I know some users use some automated mechanism to submit a high number of jobs in a row to any of these services, which are called asynchronously.At some point someone suggested to call these services synchronously instead, but we are unsure about what is the best service mode (sync vs async) for this scenario. Any idea? I’ve searched in FME Server/Flow documentation to no avail. 

Hi,I'm trying to upgrade a FME Flow Hosted instance, but I can't create snapshots from the backups tab, because I get this message "Snapshots not supported for unsupported instances"...How can I get a snapshot of my current instance to restore in the new one ?Thanks 

Hi, I recently switched FME Flow Desktop to a new machine and missed exporting my web connections. Is there a way to download them from FME Hosted?
