If the Proxmox VE special agent could not collect snapshot data for a VM (for example because the node hosting it could not be queried), the Proxmox VE VM Snapshot age service of that VM crashed with a ValidationError for SectionSnapshots.

Such VMs are now treated as having no snapshot data: no service is discovered for them, and an existing service goes UNKNOWN because its item is not found in the monitoring data. VMs with snapshot data are monitored as before.
