There was a problem hiding this comment.
Maybe call await request.stream() or body() right at the end to ensure that there are no regressions? Maybe it'd be relevant to do the same in the rest of tests as well, just to make sure in all cases we still have access to the whole request stream/body?

Starlette/FastAPI is internally caching the request body if read via
request.json()orrequest.body()but NOT when usingrequest.form(). This leads to a problem when our Sentry Starlette integration wants to read the body data and also the users code wants to read the same data.Solution:
Force caching of request body for
.form()calls too, to prevent error when body is read twice.The tests where mocking
.stream()and thus hiding this problem. So the tests have been refactored to mock the underlying._receive()function instead.Fixes #1675
