Error when creating Assistant in Microsoft Foundry using Fabric Data Agent
- Jan 14, 2026
I was able to resolve the issue by assigning the project’s service principal with Contributor permissions in the Fabric workspace. I noticed that, for some reason, Foundry does not respond properly when the Data Agent is connected to a semantic model. Therefore, I migrated the data to a Lakehouse, and it worked as expected.

Hi felipenevia,
May I know how you do "..by assigning the project’s service principal with Contributor permissions in the Fabric workspace. " , I am not able to add into a security group, hence can't add to Fabric workspace.
