Hi,

Am constantly seeing the below error when connecting my fabric data agent to co-pilot studio supervisor agent. It worked the 1st time and then keeps showing me this error.

Please help!

Best.

Hello arjunjalan,
The error message 'Agents' isn't recognized indicates that Copilot Studio is unable to find the Fabric Data Agent reference. To resolve this, you can:

Remove and re-add the Fabric Data Agent in the Supervisor Agent.

Re-publish both agents—start with the Fabric agent, followed by the Supervisor agent.

Ensure both agents are in the same Power Platform environment. The cr59e_ prefix is tied to the environment, so any mismatch will disrupt the reference.

Hi,

How do I ensure the "environments" for a co-pilot super visor agent and the two fabric agents are the same ?

Best,

Arjun

Hello arjunjalan,
When adding agents as plugins in the Supervisor, the picker displays only agents from the same environment. If you don't see your Fabric agents listed, they may be in a different environment.
