proxyox的github操作出现Terraform计划错误

我用Proxmox试用了Terraform,效果很好。尝试使用自托管GitHub runner学习和利用GitHub操作功能

  workflow_dispatch:
env:
  PM_API_URL: ${{ secrets.PM_API_URL }}
  PM_API_TOKEN_ID: ${{ secrets.PM_API_TOKEN_ID }}
  PM_API_TOKEN_SECRET: ${{ secrets.PM_API_TOKEN_SECRET }}
  ROOT_CT_PASSW: ${{ secrets.ROOT_CT_PASSW }}
  PM_TLS_INSECURE: ${{ secrets.PM_TLS_INSECURE }}
jobs:
  terraform:
    runs-on: "self-hosted"
    steps:
      - name: Checkout
        uses: actions/checkout@v3


      - name: Terraform Init
        id: init
        run: terraform init

      - name: Terraform Plan
        id: plan
        run: terraform plan -no-color

按计划,这是一个错误,尽管我已经在回购中设定了秘密。有人能指导或指出参考资料吗

  with provider["registry.terraform.io/terraform-for-proxmox/proxmox"],
  on provider.tf line 12, in provider "proxmox":
  12:   pm_api_url = var.pm_api_url

Planning failed. Terraform encountered an error while generating this plan.
