Whichever works best for you. :shrug: It is also a matter of personal preference. I like to use the Docker container.

I am also able to reproduce it by using https://github.com/dunglas/symfony-docker as a skeleton setup, then changing the default `routes.yaml` to: ```yaml controllers: resource: ../src/Controller/ type: attribute prefix: nl_NL: /nl ```...

If I remove the dev routes loaded by the framework bundle, then dump the `CompiledUrlGeneratorDumper.php` variables before it actually fails, I have the following, which shows why it fails: ```...
