Access Azure Key vault through Azure function in Fabric Data factory

Question

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.

Answer 1

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.
