Describe your environment

OS: Linux
Python version: 3.13
SDK version: 1.38.0
API version: 1.38.0

What happened?

I'm facing the same exact issue described on a previous issue #4698

When publishing a python web app on azure i get the following error _"ImportError: cannot import name 'ExtendedAttributes' from 'opentelemetry.util.types'".

Steps to Reproduce

create a app.py file with the following code

import chainlit as cl

@cl.on_message
async def main(message: cl.Message):
    # Your custom logic goes here...

    # Send a response back to the user
    await cl.Message(
        content=f"Received: {message.content}",
    ).send()

this is the content of requirements.txt

chainlit

publish to azure web app with startup command "chainlit run app.py", and then the mentioned error occurs

Expected Result

no error regarding the import

Actual Result

Connected!

Can you paste the content of the file please? Maybe something is overriding it?

I am also running into this issue, my code is failing with these imports

In the source code, opentelemetry-sdk and opentelemetry-api both have a util folder but only opentelemetry-api has a util/types.py file. Could the issue be related to this?

i will investigate this but in the meantime in order to find a solution i started to experimenti with azure container
with containers this issue does not exist, and also i'm not able to reproduce it in a local virtual environment
it happens only with azure web apps deployed as zip code

The sdk one is opentelemetry/sdk/util/. @vvbauman are you also seeing this when running stuff on azure?

Yes, I am only seeing this import error when running my code as a .whl in azure Databricks (I haven't tried running in any other Azure service). When I run locally, I have no issues, the imports work fine.

I'm going to try running as regular .py files in Databricks
