Rolling Back an Add-on Instance

Function

This API is used to roll back the version of an add-on instance to the source version. Only when status.isRollbackable is set to true, and the add-on instance is in the running, available, abnormal, upgradeFailed, or rollbackFailed state, the version can be rolled back to the source version.

Calling Method
