Can't terminate a Amp\Http\Server\Request without first consuming the body stream

[Pato05]

As the title says, if you return an Amp\Http\Server\Response without first consuming the body stream, the server crashes.

Here is the interested stack trace:

Exception: Cannot get return value of a generator that hasn't returned in vendor/amphp/amp/lib/Coroutine.php:123

I tried to reproduce this but cannot. I notice gc_collect_cycles is in the stack trace, it seems like the generator that is throwing may have been destroyed which is why it is invalid? Not sure what could have been going on here.

I need more information or a script to reproduce this to fix this. As this is a fairly old issue, I'm going to close this. Feel free to reopen it if you have any more information.
