Check for Typographical Errors

Simple typos in service names (gestion_conge.congeservice) or service arguments can cause this error. Ensure that every related service name and alias is correctly spelled and matches the service definition.

Clear and Rebuild the Cache

Symfony's cache can sometimes retain outdated configurations, leading to this error. You can clear the cache using the following command:

Inspect Registration and Autowiring

Ensure that your service is registered for autowiring if you rely on this feature. Make sure that the CongeService class has the necessary annotations or configuration settings to be detected automatically.
