Error: Cannot read properties of undefined (reading 'head')

[rj93-finseta]

I am attempting to use the action but I'm getting the following error:

Run borchero/terraform-plan-comment@v2
  with:
    token: ***
    working-directory: src
    planfile: plan.tfplan
    terraform-cmd: terraform
    header: 📝 Terraform Plan
  
Render plan
Render comment
Error: Cannot read properties of undefined (reading 'head')

There is no expanded out under the render plan, or render comment steps (not sure if there should be).

Running ls -la src outputs:

drwxr-xr-x 3 runner docker 4096 Sep 23 10:53 .
drwxr-xr-x 6 runner docker 4096 Sep 23 10:53 ..

-rw-r--r-- 1 runner docker   98 Sep 23 10:53 main.tf
-rw-r--r-- 1 runner docker 5337 Sep 23 10:53 plan.tfplan

Any ideas what could be causing this?

Is the workflow called from a pull_request event? I think this would cause the error (which should probably be improved...).

[rj93-finseta]

I have an open PR, and I am pushing commits to it. So I have:

on:
  push:

in my workflow

[borchero]

I see! Your workflow requires the trigger

on:
  pull_request:

as, otherwise, the action does not know which PR to post a comment to. In a push event, the context only provides the branch name and not the pull request(s) that the branch is associated with.

Now do we skip posting when we have a workflow with both:

on:
  push:
    branches:
    - main
  pull_request:
    branches:
    - main

[borchero]

Now do we skip posting when we have a workflow with both:

Yes, exactly. You'd need to add if: github.event_name == 'pull_request' to the workflow step which uploads the comment.
