Need to test that within the next days. This was on a production system and I cannot break it again to get the output.
What PVE version are you testing against?

The version v1.11.0 is old. If so far the problem is something else. Have you updated Proxmox VE?

Best regards

As written before, we are using PVE 6.4.x in the cluster where the error appeared. This cluster cannot be updated at the moment. Please make notes to the tool version if compatibility to specific/older PVE versions ist lost. Thanks!

Compatibility shouldn't be an issue. Try the latest version on a test machine. I use for development 6.4-13. There should be no problem.

@DerDanilo commented on GitHub (Dec 11, 2021):

The permission did not change and it was working fine in the past. Apparently the tool now also needs storage.audit permission.
Datastore.Audit VM.Audit VM.Snapshot --> With that it seems to work.

Maybe you can improve the output to let the user know that this might be a permission issue, also showing what permissions are required at least.
Also I could not find any information on how to configure the pve snapshot user in your documentation and also not in the Github readme. Can you please add that information?

Thanks!

Hi,
the required permissions are: VM.Audit, VM.Snapshot, Datastore.Audit, Pool.Allocate.
To update the documentation.

Best regards
