Web Service Configuration Pieces Disappearing when FME Flow Used as Connection Store

When we’re using FME Flow as our Connection Store. We’ve been noticing that some parameters of webservices start to disappear or change. Examples: Redirect URLs go blank, configuration of headers change, etc. We’ve been seeing this phenomenon in our AGOL web services and SharePoint List web services. 

Has anyone else seen this type of behavior?

Here is our setup:

  • FME Form/Flow: 2025.1.2 (Build 25630)
  • FME Flow is a distributed deployment (1 core + 5 engine machines)
  • Accessing FME Form (and the Connection Store) via Citrix/Azure Virtual Desktop

To resolve the issue: We either have to fill the in blanks/fix the issues or drop the web connection and web service completely and start from scratch.

We’re just trying to understand what might be causing this.

Thanks in advance!

(I am sure this isn’t the correct Category, but nothing else fit as an option here.)

Started writing the below, but then realised you’re talking about accessing them in Form:
 

There was a UI bug floating around a while back (a couple of years ago) that would result in similar behaviour. (i’ve done a brief search but can’t find it)

What was happening was that the DOM was fully loading before the backend REST calls were completed, therefore resulting in some page elements not loading/populating. Usually a refresh (or two) would make the missing values visible.

 

If you load up the same connections in Flow (via your browser) are the missing values there?

@hkingsbury Thanks for your response.

In the version we’re currently using (2025.1.2), I am not seeing an option to ‘upload’ a web connection and/or a web service via the browser. I can upload the web service to FME Flow if I am using a connection store that isn’t FME Flow (i.e. local directory, shared directory, etc.)

Or are you referring to uploading via FME Flow REST API? If so, I haven’t tried that method yet.

We’ve been seeing weird behavior since migrating to this new Citrix/Azure Virtual Desktop platform. Just curious if that may be part of the problem.
