Terraform plan produces invalid out file

[tr00p86]

Hi,

I am trying to use the out file of terraform plan to convert to .json in order to apply some policy-as-code.

• Terraform show -json out.file > out.file.json from the github action produces invalid JSON.
• I am trying to use another tool called jfson that tells me the out file is not a valid plan file.

Anyone is able to produce a valid out file from this github action and convert to JSON?

I'm trying to consume the out file as part of executing terraform-compliance and i get the following error:

ERROR: Failed to convert terraform plan file to JSON format via terraform. Here is the error :

. Converting terraform plan file.
None

Error: Error loading state: state snapshot was created by Terraform v0.13.1, which is newer than current v0.13.0; upgrade to Terraform v0.13.1 or greater to work with this state

My state file was saved with Terraform 0.13.1 and my GitHub Action is executing with Terraform 0.13.1 so I'm not sure what's up here.

Edit: See comment below: #42 (comment)

@heathsnow I think you need to declare the terraform_version?

steps:
- uses: hashicorp/setup-terraform@v1
  with:
    terraform_version: 0.13.1

I think my issue was on the terraform-compliance side of things so safe to ignore my comment above :). That and I don't remember what my workflow was at the time :P

If you need to use the output of the command somewhere else you'll need to do the following:

    - uses: hashicorp/setup-terraform@v1
       with:
         terraform_wrapper: false

... Some stuff...

      - name: Terraform Plan
        run: terraform -chdir=terraform/workspace plan -out=tf.plan
      - name: Terraform JSON output
        run: terraform -chdir=terraform/workspace show -json tf.plan > tfplan.json
      - name: Do something with the plan
        uses: actions/terraform-plan-user
        with:
          tf-plan-json-file: tfplan.json

Otherwise the JSON will have gone through sanitization and will look like:

***"format_version":"0.1","terraform_version":"0.14.11","planned_values":***"outputs":***"project_number":***"sensitive":false,"value":"7109834098491"***,"root_module":***"child_modules":[***"resources":...

Which is really confusing since all the docs say that terraform_wrapper: true will help with output usage in subsequent steps when it does the opposite.
