Problem The Azure Function App, after being deployed, is unable to retrieve data from the Data Agent configured in Microsoft Fabric. This issue does not occur when running the Function App locally.
What Have I Done Created a Data Agent in Microsoft Fabric. Integrated the Data Agent with an AI Foundry Agent. Verified that the Function App can successfully fetch data from the Data Agent when run locally. Turned on the Managed Identity to the Function App. Assigned the Managed Identity the Azure AI Developer and Administrator roles. Confirmed that AI Foundry is able to retrieve data from the Data Agent as expected.
What Is Expected After deploying the Function App to Azure, it should be able to retrieve data from the Data Agent in the same way it does during local testing.
Got a response from the product team: this is a known issue—Fabric doesn't support service principals yet. The team is working on it, but there's no timeline for a fix.
