Error Codes - Error Management
| Description
|
An error is defined by two values: a general code number describing the kind of error, and string literal helpful to understand the true reason of failure.
Here is the list of possible error codes returned by commands, and their meanings:
| Error Code | Error description
|
| 400 ERR_CMD_SYNTAX | The invoked command signature is false.
|
| 404 ERR_OBJ_NOT_FOUND | The requested specified object was not found.
|
| 401 ERR_UNAUTHORIZED | User does not have sufficient permission to execute this command.
|
| 451 ERR_OBJECT_EXISTS | The specified object does already exist and cannot be created.
|
| 500 ERR_SRV_INTERNAL | An unexpected error occurred (database connection?).
