Python Error on FME Flow for ArcGISOnlineConnector
I use the ArcGISOnlineConnector (3.10) on FME 2024.2.1.0
On FME Form everythings works perfect. When I try to run it on FME Flow it still seems to finish the workspace, but it Fails and somewhere in the log is the following lines:
1002 2025-7-10 15:31:05 | Message Type: fme::internal::_v0::py::Exception 1003 2025-7-10 15:31:05 | Python Exception <ValueError>: API not configured 1004 2025-7-10 15:31:05 | Error encountered while calling method `input' 1005 2025-7-10 15:31:05 | ArcGISOnlineConnector_CALLER (PythonFactory): PythonFactory failed to process feature
Anybody an idea what the issue could be?

Hi @matthieuv, I haven’t seen it myself. Can other workspaces on Flow using the connector? If all are receiving the same error, it might be worth reinstalling the ArcGISOnlineConnector package with the latest version.
In FME Flow:
Go to Resources > Engine and delete the fpkg file for the package name and version you want to remove.
Then go into Resources > Engine > Packages > <fmebuild>-<OS>, and look in each of the subfolders for a folder named after the package and version. Remove any folders (or files) that match the name and version of the package you are removing.
In FME Form:
Upgrade to the latest package and republish the workspace with the package to FME Flow. The first time the workspace is run, the new package should be installed. You can check the fmeprocessmonitorengine.log file to see if it installed successfully.
Other than that, in the job log, is the Python interpreter being loaded the on that is expected (set in the Workspace Parameters > Scripting)? Or is there some other interpreter being loaded, perhaps a custom one. The full job log may help.
I have to file this tip away for safe keeping. Deleting packages in flow and updating is a great troubleshooting tip. Thanks @mattmatsafe
Late follow up, but problem hasn't been resolved yet. I tried removing the package and installing again by running the workspace.
For your information, this has worked before but somehow stopped working.

Are there any more clues in the other logs? Sometimes I’ve seen python error messages skip the FME Workspace but get reported in the fmeprocessmonitorengine.log. There could be more clues in there
I notice now two interesting things.
After running the workspace with my admin account the workspace doesn't immediately stop after the Python error, but continues to process the workspace. No data is written though.
The other interesting thing is the following errors I see in the log fmeconnection.log when running as admin. When I run as a normal user they don't appear.
