Xdebug with PhpStorm/Idea and Symfony in docker-compose: Breaks only at first file index_dev.php

I am using Idea Ultimate with PHP plugin.
phpinfo() seems ok and I have validated the configuration with the idea script.

enter image description here

The request used is http://localhost:8080/web/index_dev.php/create-file. I can put a breakpoint anywhere in index_dev() or use xdebug_break();

But I can’t stop one file later, such as the Symfony controller.

I have a message saying Debug session was finished without being paused and propose a mapping between the docker instance and my local volume.

enter image description here

Looks fine to me, and it’s able to find the index_dev.php inside this main directory.

So where can be the problem ?
