}
HTTP Status When it occurs
400 Bad Request One of these: organizationID, dataSource, or queryId contains invalid characters, a mandatory parameter is missing, a parameter value fails validation, an unsupported comparison operator is specified, a column name in response_columns is not recognised, start_time is not before end_time, limit is out of range, or offset is negative.
404 Not Found Either the dataSource is not registered for your organization or the queryId does not exist.
500 Internal Server Error An unexpected error occurred on the server. Retry the request. If the problem persists, contact support.
Note: Validation stops at the first error encountered. Fix the reported issue and resubmit.
