Hey @Isi 

I'm using a single-node cluster with DBR 14.3 LTS, and Unity Catalog is enabled. I also tried DBR 15.x LTS, but the issue persists.

I set up the workspace using the quickstart method, which created four Databricks roles—two for Lambda, one for EC2 instance setup, and one for S3. These roles are linked to my workspace. The cluster configuration shows "None" for the instance profile.

I also tried enabling credential passthrough, but nothing worked.

Is there any other fix for this?
