Add support for error responses

[joelalejandro]

The hook should be usable in the error hook. JSON API has a spec regarding errors:

Error objects provide additional information about problems encountered while performing an operation. Error objects MUST be returned as an array keyed by errors in the top level of a JSON API document.
An error object MAY have the following members:

• id: a unique identifier for this particular occurrence of the problem.
• links: a links object containing the following members:
• about: a link that leads to further details about this particular occurrence of the problem.
• status: the HTTP status code applicable to this problem, expressed as a string value.
• code: an application-specific error code, expressed as a string value.
• title: a short, human-readable summary of the problem that SHOULD NOT change from occurrence to occurrence of the problem, except for purposes of localization.
• detail: a human-readable explanation specific to this occurrence of the problem. Like title, this field’s value can be localized.
• source: an object containing references to the source of the error, optionally including any of the following members:
  • pointer: a JSON Pointer [RFC6901] to the associated entity in the request document [e.g. "/data" for a primary data object, or "/data/attributes/title" for a specific attribute].
  • parameter: a string indicating which URI query parameter caused the error.
• meta: a meta object containing non-standard meta-information about the error.
