@zqumei0 merge in current main. I tested it locally and had no issues with tests. Should be good on pipeline. After this, mention maintainer or approver to run it.

I don't get why those tests are failing. It worked on my machine. Can anyone help out with debugging?

Weird, I checked out this PR with gh co 1900. Tried running tox -e py311-test-instrumentation-httpx18 -- -rf. It first failed until I added these changes:

After that, it also failed but by different reasons. @zqumei0 can you please check this?

Hi 👋 I could also use this feature, although I don't quite have the time to deeply contribute other than do some testing on my end. In an attempt to be useful, I tried following the steps to get started and at least run the tests on my machine. However, the tests were also failing for me.

@macieyng I would have dug into the test logs in GitHub Actions but it looks like the logs have expired at this point ☹️

I tried the steps that @ocelotl laid out but it didn't work either.

After installing the dependencies in the requirements.txt files, I ran this command: tox -e py311-test-instrumentation-httpx18 -- -rf

And here was the output:

@zqumei0 if you or anyone wants to pick up this PR, I'm happy to do some testing and give some feedback.
