Exception thrown using the Symfony profiler for Messenger workers

[dev-cld]

Hello,

Listening to Symfony Messenger workers raises a BadRequestException from Symfony\Component\HttpFoundation\Request.

It seems to be due to the introduction of a rejection of some characters in the URIs, including backslashes, by the Request class of the HTTPFoundation component:
symfony/http-foundation@32310ff#diff-de5d8eb3f1d6537c947f70e0a4673779312a902c083739f472c709c037bcbc30R370

if (false !== ($i = strpos($uri, '\\')) && $i < strcspn($uri, '?#')) {
    throw new BadRequestException('Invalid URI: A URI cannot contain a backslash.');
}

Backslashes are used by the bundle in the transaction name, which is composed from the class name of the message, and the class name uses backslashes for the namespace:

instrumentation/src/EventListener/MessengerProfilerListener.php

Line 37 in e33e7be

$transactionName = \get_class($event->getEnvelope()->getMessage());

instrumentation/src/Messenger/ProfilerMiddleware.php

Line 32 in e33e7be

$transactionName = \get_class($envelope->getMessage());

Then the SymfonyProfiler uses the transaction name in the URI:

instrumentation/src/Profiler/SymfonyProfiler.php

Line 48 in e33e7be

$uri = sprintf('http://%s/%s', $kind, $name);

And creates the Request:

instrumentation/src/Profiler/SymfonyProfiler.php

Line 50 in e33e7be

$this->request = Request::create($uri, $kind);

I suggest fixing it by replacing the backslashes in the class name with regular slashes:

$transactionName = str_replace('\\', '/', \get_class($event->getEnvelope()->getMessage()));

$transactionName = str_replace('\\', '/', \get_class($envelope->getMessage()));
