[terraform] plan failed

  1. terraform plan ends up with errors
Error: The terraform-provider-proxmox_v2.9.10 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.

When I set the TF_LOG to ERROR, I can see these errors many times:

  1. Check remote tfstate

Pull the remote tfstate

ᐅ terraform state pull > current.state

Compare the number of returned errors and the number of disk/node in tfstate:

ᐅ terraform plan -out plan.staging 2>&1 | grep "Error.*bool is required" | wc -l
26

ᐅ grep '"backup": 0' current.state | uniq -c
