Original GitHub issue: https://github.com/Corsinvest/cv4pve-autosnap/issues/54

I'm using the latest version of cv4pve-autosnap (1.11) on Proxmox version 7.0-13. When trying to create snapshots via
cv4pve-autosnap --host=127.0.0.1 --api-token='root@pam!snapshots=<token>' --vmid="all" snap --label=test --keep=1
the script fails and throws an exception with the following output:

ACTION Snap

Label:            test

This might sound so stupid, but I just wanted to try and run the command with the --debug option, but tried it "normally" beforehand and it just worked. I have no idea why. I haven't changed anything. Ig this issue can be closed?
I'll reopen when I can reproduce it. As of now it seems resolved. strange...
