Not possible to run on specific comment?

[dedesvik]

I want to run this regex match only on a specific comment.

eg.

1. My github-actions [bot] makes a comment if another action runs
2. This action parses the comment the bot makes using regex (example here: https://regex101.com/r/SpeOZS/1)
3. The regex match value is sent to a metadata.json file

The issue I have is that this action does not seem to be able to parse a comment made by the github-actions [bot]

Is it not possible?

Here's my actions workflow:

name: Parse comment
on:
  pull_request:
      types: [edited]
jobs:
  parse_comment:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2

      - uses: peter-evans/find-comment@v1
        id: bot
        with:
          issue-number: ${{ github.event.number }}
          body-includes: "<!-- GH BOT -->"
      - run: |
          echo ${{ steps.bot.outputs.comment-id }}
          echo ${{ steps.bot.outputs.comment-author }}

      - uses: actions-ecosystem/action-regex-match@v2
        id: description
        with:
          text: ${{ github.event.comment.body }}
          regex: '^[A-Za-z_]+:\s+(.*)$'

      - uses: actions-ecosystem/action-regex-match@v2
        id: justification
        with:
          text: ${{ github.event.comment.body }}
          regex: '^[A-Za-z]+:\s+(.*)$'

When I try to print the values of description and justification at the end of the workflow with:

      - name: Print comment body  ## A step to print the body would be nice
        env:
          description: description
          justificaton: justification
        run: |
          echo description
          echo justification

They are always empty.

Ok I figured out one part of this issue. I was stupidly telling the regex action to run on the main comment not the bot comment (as shown above in the first comment). So I modified the workflow as such:

From:

      - uses: actions-ecosystem/action-regex-match@v2
        id: description
        with:
          text: ${{ github.event.comment.body }}  ## Here it's checking the main PR author's comment
          regex: '^[A-Za-z_]+:\s+(.*)$'

To:

      - uses: actions-ecosystem/action-regex-match@v2
        id: description
        with:
          text: ${{ steps.bot.outputs.comment-body }}  ## Here it's checking bot's comment
          regex: '^[A-Za-z_]+:\s+(.*)$'

the 'bot' var in this case is the action id I gave to a step above this, which finds the comment ID using this action.

Now the actions runner finally gives me the readout I wanted:

Run actions-ecosystem/action-regex-match@v[2](LINK_REDACTED)
  with:
    text: <!-- GH BOT -->
  **Hello, @dedesvik!**
  **This component is critical!**
  **Edit and input the following BEFORE approving the PR!**
  ___
  * change_description: test
  * justification: change
  
  The last change was authored by:
  @dedesvik
    regex: ^[A-Za-z_]+:\s+(.*)$

Last step is to save the regex match as a variable to pipe into my desired file.
