Description

The bug is a deprecation that is triggered because the usage of a null argument to \trim() method in \Symfony\Component\HttpKernel\DataCollector\LoggerDataCollector. (L147)

This bug appears in dev environment because I added a monolog handler that logs every deprecation in a file.

How to reproduce

I created a reproducer that explain step by step how to reproduce this bug and what is the cause.

Possible Solution

This bug can be fixed in vendor/symfony/http-kernel/DataCollector/LoggerDataCollector.php:147 by checking if $log['channel'] is not null before using the \trim() method.
