Not working for user assigned MSI apptype

[arshad98786]

Hi Team,

I’m trying to send a request using Python without providing an app password, as the authentication method is set to User Assigned Managed Identity (userAssignedMSI). However, the Python code sample provided still expects an app password, which should not be required for this authentication type.

Could you please help me resolve this issue at the earliest?

Thanks and Regards,
Arshad Ali S. K.

To authenticate using a User Assigned Managed Identity (userAssignedMSI) in Azure without providing an app password, you can use the azure-identity library in Python. This library allows you to authenticate using managed identities, which is a secure way to access Azure resources without needing to manage credentials.

Hi @Prasad-MSFT ,

We tried the recommended solution but we are getting the same error we faced before.
I am pasting the error message below

The above error is occurring for the below line of code.
await turn_context.send_activity("This is a hardcoded reply")

Could you please help out with this error we are facing.
Thank You.
