Errors

If a service call causes an exception that is not caught by the service itself then Terrain will respond with a standardized error message:

{
    "error_code": "ERR_UNCHECKED_EXCEPTION",
    "message": reason-for-error
}

The HTTP status code that is returned will either be a 400 or a 500, depending on which type of exception is caught. In either case, the reason for the error should be examined. If the logging level is set to error or lower then the exception will be logged in Terrain's log file along with a stack trace. This can be helpful in cases where the true cause of the error isn't obvious at first.
