When I have 2 or more user Identity. Then using python API "DefaultAzureCredential" is failing.

Question

When I have 2 or more user Identities for one node(VM), my API call fails. But With one it is working.

I want a way to make it work. because users can have multiple user Identities.

API I am using.

 try:
        credential = DefaultAzureCredential()

Error
