class UnprocessableHttpEntityExceptionNormalizer in Drupal 8

Normalizes and UnprocessableHttpEntityException.

Normalizes an UnprocessableHttpEntityException in compliance with the JSON API specification. A source pointer is added to help client applications report validation errors, for example on an Entity edit form.

@internal JSON:API maintains no PHP API since its API is the HTTP API. This class may change at any time and this will break any dependencies on it.
