3. Run make example-destroy && make example again -- no errors 🤷🏻

Expected behavior make example should not randomly throw "invalid format" error

Screenshots N/A

Additional context Symptoms suggest there is a race condition somewhere in the provider's code. Happens only for VM, not LXC.

[bpg]

more chances to have this error on a "cold" PVE -- e.g. a test proxmox instance that was running idle.
