| # Error code | ||
|
|
||
| Nebula Graph 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](https://discuss.nebula-graph.com.cn/) or [GitHub](https://github.com/vesoft-inc/nebula/issues). | ||
|
|
||
| - When the code returned is `0`, it means that the operation is successful. | ||
