50XInternal Sourcengine server error (rare)

Sourcengine API uses conventional HTTP response codes to indicate the success or failure of an API request. Response codes in the 2xx range indicate success of the request. Response codes in the 4xx range indicate an error that failed due to a problem in the request parameters: maybe a required parameter was omitted, or an invalid MPN given. Response codes in the 5xx range mean that we had an internal error on our servers (a rare occurrence).
