Additional context
Add any other context about the problem here.

Commencez par reproduire l’échec avec le document OpenAPI de l’issue, en vous concentrant sur l’analyse des schémas et la résolution des références pour les deux schémas qui partagent le titre "ApprovementStatus". La tâche est terminée lorsque l’enum référencé est correctement résolu et que le schéma ActualApprovement n’est pas supprimé.
