Hello, Could you tell me more about this Error:* Failed to RedefineVmCheckpointsVDS, error = General Exception: ('Property xml is required',)*. It happened on creating incremental backup using ovirt sdk.

How can I fix it? I know that is not because of wrong checkpointId because I tried to use wrong Id on other environment and logs are different.
