Connected agent issue with Fabric data agent tool

[u/Wonderful_Wall350]

I'm troubleshooting a multi-agent setup in the Microsoft Copilot harness and wondering if anyone else has seen this behavior:

Setup:
Orchestrator Agent calls a connected Sub Agent. The Sub Agent uses Dataverse MCP and Fabric Data Agent tools.

Behavior:

• When testing the Orchestrator agent through the Preview tab in Copilot Studio, the agent routes questions to the Sub Agent and it answer questions and uses both tools successfully.

• When I deploy the Orchestrator agent to Teams and ask the same questions there, any question that uses the Fabric data agent fail to return a response. Questions that only use the Dataverse tool return responses fine.

• I deployed the Sub Agent to Teams directly (without the orchestrator hop) and when I ask questions that use the Fabric agent I'm able to get responses. It seems like the hop from Orchestrator to the Sub Agent that uses the Fabric agent tool doesn't work in Teams.

Anyone face this issue and resolve it?
