Thanks for the PR, I will need a bit of time to check if the major has some changes that could affect us and then I will come back to you

Looks like ServerRequest::fromGlobals got stricter now and could raise an exception in RequestFetcher in case some headers are malformed. Could you wrap it in a try/catch and return null on failure

@Litarnus Thank you for the helpful suggestion, I've fixed it. I found that GuzzleHttp\Psr7\Request::assertMethod and GuzzleHttp\Psr7\Request::assertProtocolVersion can throw a \InvalidArgumentException, so I caught it. Or would you rather catch all \Throwable instances?
