FAQ about data backflow
Q: Why are some error messages returned after data backflow?
A:
Error messages are returned to report record parsing errors. You can go to the Graph O&M page and find error logs based on the backflow ID. For example, the error message "get default value failed for field[creator]" indicates that the field is abnormal and no value is specified for the field. As a result, the entire data record fails to be written during data backflow.
A format error indicates a failure of field type conversion. For example, when a field of the STRING data type fails to convert to the INT data type, a format error occurs.
