Error code

NebulaGraph returns an error code when an error occurs. This topic describes the details of the error code returned.

Note

  • If an error occurs but no error code is returned, or if the error code description is unclear, we welcome your feedback or suggestions on the forum or GitHub.
  • When the code returned is 0, it means that the operation is successful.
