pytest-otel seems to be broken on Python >= 3.10.0

OS: Linux (Arch Linux)
Python: 3.10.4

Since Python 3.10.0, whenever I run the Python tests on Beats, more specifically Filebeat, I get this error (all tests fail):

Removing pytest-otel solves the problem in the sense the tests can run, but I am not sure about what happens with the instrumentation.

So far I've tested it with Python (using pyenv):

• 3.8.13
• 3.9.12
• 3.10.0
• 3.10.4

Unfortunately I have not had time to create a small example to reproduce it.

It seems related to OpenTelemetry open-telemetry/opentelemetry-python#2288 I will update the OpenTelemetry SDK and test if it is resolved.

[kuisathaverat]

you are testing it locally, isn't it? because I do not see errors on any of the CIs we have, IIRC we do not have any with Python 3.10 yet

[belimawr]

Yes, it's not affecting CI, just my local environment.

[kuisathaverat]

it is already fixed but not released #1664

[kuisathaverat]

the release 1.1.0 contains the fix
