Getting `Argument list too long` in GitHub Actions-CodePudding

I am following hashicopr learning guide on how to set up GitHub Actions and terraform. All is running great besides the step to update the PR with the Terraform Plan.

I am hitting the following error:


An error occurred trying to start process '/home/runner/runners/2.287.1/externals/node12/bin/node' with working directory '/home/runner/work/ccoe-aws-ou-scp-manage/ccoe-aws-ou-scp-manage'. Argument list too long

The code I am using is:

    - uses: actions/[email protected]
      if: github.event_name == 'pull_request'
      env:
        PLAN: "terraform\n${{ steps.plan.outputs.stdout }}"
      with:
        github-token: ${{ secrets.GITHUB_TOKEN }}
        script: |
