Describe a bug

Hello,
The action fail on main branches while it works on PR.
See the screenshot below and the report.json gist link

Expected behavior

The report is generated and a comment is added to the PR

Additional context

[ArtiomTr]

Hello @QuentinLemCode 👋,

Looks like the coverage file coverage/report.json has an invalid format. Please make sure you're generating a coverage file with the necessary flags: https://github.com/ArtiomTr/jest-coverage-report-action#customizing-test-script

[QuentinLemCode]

@ArtiomTr Thanks for reply
I don't see what's wrong with my report.json file.
Also the jest command line is the same than in other branches, but it fail only on main.
Can you take a look at the gist?

[ArtiomTr]

Try to specify:

        with:
          coverage-file: ./coverage/report.json
          base-coverage-file: ./coverage/report.json # this line added
          github-token: ${{ secrets.GITHUB_TOKEN }}
          threshold: 90
          annotations: coverage
          skip-step: all

This will skip coverage comparison. This is not ideal, but at least your CI will work for now. I need more time to dig deeper into this issue

Did you find time to look deeper into this yet? Just now, I could observe the same behavior:

jobs:
  coverage:
    runs-on: ubuntu-latest
    permissions:
      checks: write
      pull-requests: write
      contents: write
    steps:
      - uses: actions/checkout@v4
      - uses: ArtiomTr/[email protected]
        with:
          package-manager: yarn
          output: comment, report-markdown
          icons: emoji
          threshold: 80

The code above runs perfectly fine on PRs but breaks on main:

Could the reason for this behavior be that there is no PR context on main for the bot to comment in?

really want to use this but no matter what combination of configs I use i always get the "Error: TypeError: Cannot convert undefined or null to object" as outlined in this issue.

Hi there,

Today I got the same issue and it seems to be related with the "threshold" flag.
When I ran the action setting the threshold and I do not met it the coversion error occours.
However, it the project passed the threshold the action completes "OK".
