Python script to access Azure Service Bus with Managed identity

Question

I want to send a message to a servicebus from Visual Studio Code, in a simple python script. I want to access the service bus using a managed identity (in this case my own user). From visual studio it would be fairly simple using the authentication part in options.

As I understand it in Visual Studio Code you can use the Azure Account extension. So I installed the extension, logged in with success and can see all azure ressources.

However when i run my python script I get following error:

Its like VS Code does not pickup my credentials. Beside logging into the extention is other configurations needed?

Please don't post images of code, error messages, or other textual data. — tripleee

Python script to access Azure Service Bus with Managed identity

It worked for me using below steps:

Firstly I logged in to azure using Azure CLI command:

az login

enter image description here

Then, I had set the subscription using below command:

 az account set --subscription  <subid>

enter image description here

Given below permission or role to my self in the resource:

enter image description here

Used below code which sent the message successfully:

from azure.servicebus import ServiceBusClient, ServiceBusMessage
from azure.identity import DefaultAzureCredential as cho

rith_servicebus_name = "rith02.servicebus.windows.net"
q_name = "rith"
credential = cho()
servicebus_client = ServiceBusClient(rith_servicebus_name , credential)
rith = servicebus_client.get_queue_sender(queue_name=q_name)
with rith:
    val = ServiceBusMessage("Hello Rithwik")
    rith.send_messages(val)

Output:

enter image description here

If the above process do not work, as an alternative you can use client id , tenant and secret as client credential login.

This issue comes when you do not set the account subscription or there is a issue with environment variables. Refer SO-Thread1 and SO-Thread2 for more information.
