Is there a way we could try to avoid using _client here, and instead access what we need through a public API? I would strongly prefer to avoid using an external library's private API, since the private API could change at any time and cause problems in the future.

No, I don't believe there is a way we can avoid using _client. We can use a try/except here to be safe and log when it is unavailable. Is there a standard way to raise sentry internal warnings?

Okay, in that case, we can use capture_internal_exceptions here. I also checked that one of your unit tests is verifying this function, so we will get a test failure if _client ever gets removed
