Hi, ssrithar 

 

I noticed this same error began at 01/23/2026, but pipelines calling UDFs that interact with Lakehouses worked previously. Are there some new changes to UDF authorization, like them going from Preview to GA?

We started seeing this same error at 1/22/2026 around 3:00 AM EST on a pipeline that has been running successfully since the beginning of December. The UDF was used to call a REST API to refresh the metadata for a SQL endpoint, but after testing on a basic "Hello Fabric" UDF the error still exists, so I don't think this is related to spark or lakehouses. We were waiting 24 hours to see if it resolved itself as part of a Fabric update, but as of this morning the issue still exists for us.
