False positive error trigger when using sentry in streamlit

[RHDZMOTA]

The following error is triggered when forcing a reload of a streamlit page:

RuntimeError: generator didn't stop

Full error:

Here's the reference to the streamlit tornado implementation: https://github.com/getsentry/sentry-python/blob/master/sentry_sdk/integrations/tornado.py

And here is reference to a streamlit-dev conversation about this same issue. Apparently stopping to use cache_data may solve the problem temporarily... but the root-cause of the problem is not clear.

Is this issue solved?

This issue seems to be resolved by changing streamlit page-config code from the dataclass __post_init__ into the context manager (i.e., __enter__).

I'll keep the issue open for some time to monitor if the issue has really been resolved.

Context

We changed the streamlit page config from the __post_init__ into __enter__ to allow creating page instances without trigger the page-config setup (which can only be executed once, so initializing several classes resulted in a configuration error).
