Http parser throws 'Null check operator used on a null value' #49930

Closed annagrin closed 11 months ago

annagrin commented 2 years ago

Our customers encountered a null check failure while running the web debugger.

The check fails at https://github.com/dart-lang/sdk/blob/7d8459dc3c2e53b8fff5239bcb13c3c4f28f9666/sdk/lib/_http/http_parser.dart#L199

Update: that crashes the debugger, so the user needs to restart the session, which might take a while.

@annagrin we have a fix for this but are wondering about a test case that would reproduce the problem so we can verify the fix. Do you have any ideas on how to reproduce the issue ?
