By default, the library has an ExceptionHandler that will automatically create a status code and a response body based on the exception thrown.

Also other exception (in addition to those in this file) from kotlin-utils are considered as status-override:

• ExternalServiceHttpException → 502 Bad Gateway
• InsufficientPermissionsException → 403 Forbidden
• MalformedHeaderException → 400 Bad Request
• MalformedInputException → 400 Bad Request
• MalformedParameterException → 400 Bad Request
• RequiredHeaderException → 400 Bad Request
• RequiredFieldException → 400 Bad Request
• RequiredParameterException → 400 Bad Request
• ResourceAlreadyExistsException → 409 Conflict
• ResourceConflictException → 409 Conflict
• ResourceDeletedException → 410 Gone
• ResourceLockedException → 423 Locked
• ResourceNotAcceptableException → 422 Unprocessable Entity
• ResourceNotFoundException → 404 Not Found

You can choose your favourite body type:
