I'm getting an error when using getMetadata method with a movie ratingKey
It's working fine with a tv show ratingKey
Did I forgot something ?
Error response below

{
  "statusCode": 500,
  "error": "Internal Server Error",
  "message": "Response validation failed"
}

Example raw response with manual GET HTTP request

• XML or JSON for movie
• XML or JSON for tv show

Thanks in advance
