Packer Error: Unknown source type proxmox

I've started to get this error in Packer after I rebuilt the initialisation server.

Run /usr/bin/packer build \
Error: Unknown source type proxmox

I needed to download the Proxmox libraries from their GitHub

Added this

packer {
  required_plugins {
    proxmox = {
      version = ">= 1.1.2"
      source  = "github.com/hashicorp/proxmox"
    }
  }
}

and a new step in my GitHub workflow

      - name: packer init
        working-directory: packer
        run: |
          /usr/bin/packer init .
