Hello,

I am trying to execute an Azure function deployed on Fabric data factory that fetches Azure Key vault values. I have already assigned Key vault admin to the Fabric user . The function executes ok when I debug & execute it through Visual Studio but when executing it through the Fabric data factory it errors out with non specific error message :

I am wondering if this is achievable. I also tried accessing Cosmos DB through Azure function deployed on Fabric and even that errors out with the above error message.

    It looks like additional permissions may be required for the function app's managed identity or service principal.

    I would recommend:

    1. Check the function app's managed identity has proper permissions on the Key Vault.
    2. Fabric data factory has the necessary permissions to invoke the function.

    I found similar issues here:
