If an error occurs while processing a request, the API responds with a standard error body.

The error body is built using rules from your endpoint response configuration, such as StatusField and ShowDeveloperErrors.

    "error": "authoization",
    "error_description": "You are not authorized to set the 'name' field."

Custom Exceptions

If an exception is thrown, Firestorm derives the error value from the exception type name and the error_description from the exception Message property.

    "error": "null_reference",
    "error_description": "Object reference not set to an instance of an object."

If the exception derives from the built-in RestApiException, the StatusCode property is used to determine the HTTP response status code for this error. For example, you could use 400 Bad Request for custom validation exceptions.
