cannot import name 'Buffer' from 'typing_extensions' (/databricks/python/lib/python3.10/site-package

I am trying to add messages to an azure service bus from a notebook. But I get error from title. Any suggestions how to solve this?

import asyncio

from azure.servicebus.aio import ServiceBusClient

from azure.servicebus import ServiceBusMessage

from azure.identity.aio import DefaultAzureCredential

FULLY_QUALIFIED_NAMESPACE = "xx-dev.servicebus.windows.net"

TOPIC_NAME = "xx"

credential = DefaultAzureCredential()

async def send_single_message(sender😞

# Create a Service Bus message and send it to the queue

message = ServiceBusMessage("Single Message")

await sender.send_messages(message)

print("Sent a single message")

async def run():

# create a Service Bus client using the credential

async with ServiceBusClient(

fully_qualified_namespace=FULLY_QUALIFIED_NAMESPACE,

credential=credential,

logging_enable=True) as servicebus_client:

# get a Queue Sender object to send messages to the queue

sender = servicebus_client.get_topic_sender(topic_name=TOPIC_NAME)

async with sender:

# send one message

await send_single_message(sender)

# Close credential when no longer needed.

await credential.close()

asyncio.run(run())

print("Done sending messages")

print("-----------------------")

@Sega2 it sounds like the error occurs because the typing_extensions library version in your Databricks environment is outdated and does not include the Buffer class, which is being imported by one of the Azure libraries.

Can you first try:

%pip install --upgrade typing-extensions

Validate it:

import typing_extensions print(typing_extensions.__version__)

And then ensure the version is >=4.6.0, as this version supports Buffer.
