[DIC] Improve error message when a service is badly configured #31265
Description
When making this typo:
App\Word\WordChecker:
arguments:
checkers:
- '@App\Word\Checker\StaticWordChecker'
- '@App\Word\Checker\BannedWorldListChecker'The error is the following:
Invalid service "App\Word\WordChecker": the value of argument "checkers" of method "__construct()" must be null, an instance of Symfony\Component\DependencyInjection\Reference or an instance of Symfony\Component\DependencyInjection\Definition, array given.
Honestly, I don't understand the error. IMHO, we could improve it
We could add Did you forgot to prefix $ to checkers ?
(Question: Did you get the error at the first glance ? 😂 )
