when starting a deployment workflow fails with: HttpError: invalid json response body

[airtonix]

below is a typical implementation for us :

We start a deployment:

    - name: start deployment
      uses: bobheadxi/deployments@v1
      if: inputs.DeployStage != ''
      id: deployment
      with:
        step: start
        token: ${{inputs.GithubToken}}
        env: ${{inputs.DeployStage}}/netlify/${{inputs.DeploymentName}}
        desc: ${{inputs.DeployMessage}}

then when done, we mark the deployment as done:

    - name: update deployment status
      uses: bobheadxi/deployments@v1
      if: inputs.DeployStage != ''
      with:
        step: finish
        token: ${{inputs.GithubToken}}
        status: ${{job.status}}
        env: ${{steps.deployment.outputs.env}}
        env_url: ${{steps.netlify.outputs.deploy_url}}
        deployment_id: ${{steps.deployment.outputs.deployment_id}}

We've now had to put in some esscape hatches into our workflows while we wait for your resposne (viz if: inputs.DeployStage != ''), otherwise we get the following error everytime.

Run bobheadxi/deployments@v1
  with:
    step: start
    token: ***
    env: pr/1123/netlify/AppStorybook
    desc: Deploy preview pr/1123
    debug: false
    auto_inactive: false
  env:

This started happening for us in 1.3.0 now and we tried to update to 1.4.0 and it has the same error.
