5.6 Error Codes
This article mainly introduces the error codes of Arklet, ModuleController, and KouplelessBoard.
ErrorCode Rules
Two-level error codes, support dynamic combination, using PascalCase, different levels of error codes can only be separated by “."
such as Arklet.InstallModuleFailed
Level 1: Error Source
Level 2: Error Type
Suggestion
Briefly explain the solution for upstream operations to refer to.

Level 2: Error Type
| Business Type | Error Source | Error Type | Meaning | Solution |
|---|---|---|---|---|

| ModuleController | ResourceConstraned | Resource limited (thread pool, queue, etc. full) | Please retry later | |
| Installation Related | Arklet | InstallModuleTimedOut | Module installation timed out | Please retry |
| Arklet / User | InstallModuleFailed | Module installation failed | Please check the failure reason | |
| Arklet | InstallModuleExecuting | Module is being installed | The same module is being installed, please retry later | |
| User | DiskFull | Disk full | Please replace | |
| Uninstallation Related | OtherUpstream | EmptyIPList | IP list is empty | Please enter the IP to be uninstalled |
| Arklet | UninstallBizTimedOut | Module uninstallation timed out | Please retry | |
| Arklet | UninstallBizFailed | Module uninstallation failed | Please check | |
| Base Related | ModuleController | BaseInstanceNotFound | Base instance not found | Please ensure that the base instance exists |
| KubeAPIServer | GetBaseInstanceFailed | Failed to query base information | Please ensure that the base instance exists | |
| ModuleController | BaseInstanceInOperation | Base instance is under operation | Please retry later | |
| ModuleController | BaseInstanceNotReady | Base data not read or base is not available | Please ensure that the base is available | |
| ModuleController | BaseInstanceHasBeenReplaced | Base instance has been replaced | Additional base instances will be added later, please wait | |
| ModuleController | InsufficientHealthyBaseInstance | Insufficient healthy base instances | Please scale out | |
| Scaling Related | ModuleController | RescaleRequirementNotMet | Scaling conditions are not met | Please check if there are enough machines for scaling/Check the scaling ratio |
⚠️ Note: The base runs on different base instances, such as pods. Therefore, BaseInstanceInOperation, BaseInstanceNotReady, BaseInstanceHasBeenReplaced, InsufficientHealthyBaseInstance error codes may refer to both the application status of the base and the status of the base instance.
