"description": "fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field...

                        All valid rules within a Route attached to this Listener should be
                        implemented. Invalid Route rules can be ignored (sometimes that will mean
                        the full Route). If a Route rule transitions from valid to invalid,
                        support for that Route rule should be dropped to ensure consistency. For

 * If you use masked losses with Keras the loss values may be different in TensorFlow `2.12` compared to previous versions.
 * In cases where the mask was previously ignored, you will now get an error if you pass a mask with an incompatible shape.
