Maybe add a comment why this is needed?
Waiting for a fixed amount of time is of course far from ideal, but if it resolves or at least significantly mitigates the flakiness, it's fine to have it, as flakiness has really been getting into the way recently.
Edit: Whoa, samples tests passed on the first attempt. Could be a coincidence, of course, but it's a good start nevertheless. 🙂

Fixes #341 🦕
The stream sometimes gets removed (
UNKNOWNerrors) before the subscriber can successfully pull messages. Pausing to give the subscriber some time to reconnect since this subscription (subscription_sync) is used in two different synchronous pull samples:If this doesn't fix the flaky test, I will consider using two different subscriptions for the two different sync pull samples tests.
The delete schema sample test failure is unrelated. It's known and is flaky due to backend issues.
