As described in this comment, it looks like whenever the terraform Proxmox provider attempts to use the api to get a VM by reference, it crashes:

Stack trace from the terraform-provider-proxmox plugin:

panic: interface conversion: interface {} is nil, not []interface {}

Error: The terraform-provider-proxmox plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.
