Hi everyone,
I’m encountering an issue with a published feature layer that includes a polygon layer and several related tables.
The relationships work perfectly in both PostgreSQL (the database) and ArcGIS Pro. I can see all related records without any problem. However, after publishing the layer as a feature service, the relationships appear in the table as expected, but clicking the link to view related records returns nothing.


When checking the server logs, I found two errors: Error: Invalid query; Unable to perform query operation

I’ve tried various troubleshooting steps but haven’t been able to resolve this. Does anyone have an idea of what might be causing this or suggestions on how to fix it?
Any help is greatly appreciated!
Thanks in advance!
