Fixing:
The reason is that the configuration data in xpath does not exist in the datastore. Such as deleting a node that does not exist.
When encountering such an error, user can get configuration data in the board with get-config command, and check
whether the operation type(add/delete/modify) of the node in the path is reasonable or not,.
