Represents an
HTTP 500 Internal Error response. This status indicates that the server failed to successfully process the request. This generally means that the server is misbehaving or is misconfigured in some way, although a misbehaving server might also send this status code in the case of a bad request message (although it should not do this; an HTTP 4xx response is more appropriate in that situation).
Note that a complete list of RESTful exceptions is available in the Package Summary.
