Unable to use python AIOHTTP integration with gunicorn + eventlet, claims aiocontextvars is not installed

[TheSHEEEP]

Here is the output trying to run the gunicorn service:

I have read in other issues that gevent (and therefore I guess eventlet, too?) interferes with the aiocontextvars package somehow.
Am I simply out of luck in this case if I cannot switch to Python 3.7?

Even on Python 3.7 you will have problems getting gevent to harmonize with contextvars/aiocontextvars. The blocker here is gevent itself: gevent/gevent#1407 this still needs to be released, and then we'd have to update the sanity checks in the SDK to allow those gevent versions.

We don't support aiohttp in your scenario because without working contextvars we are unable to prevent contextual data (breadcrumbs, contexts, http request data) from leaking into unrelated errors.

[TheSHEEEP]

I see. Thanks for the explanation.

It would be nice if this information could be added to the documentation, though:
https://docs.sentry.io/platforms/python/aiohttp

[untitaker]

Yes we also need to make the error message more informative here.

gevent 20.5 is out which fixes this problem
