Getting an Error 500 but the API still worked

I’m using the ‘Duplicate e-learning course’ in the Docebo API browser, and while the API does duplicate a course I always get an internal service error each time I use it. Is there a reason why this endpoint returns an error?

{
  "name": "Internal Server Error",
  "message": [
    "An internal server error occurred."
  ],
  "code": 0,
  "status": 500
}
