Action failing due to Cannot read properties of undefined (reading 'numFailedTests') error

[Metaphysics0]

Describe a bug

the action is failing due to

Error: TypeError: Cannot read properties of undefined (reading 'numFailedTests')

this error gets printed very shortly after the generating report log.

I can run the command just fine:

npx --ci --json --coverage --testLocationInResults --outputFile=report.json

and the report.json gets added to the root directory of my project with the correct fields.

Expected behavior

Not getting the numFailedTest logs

Details

• Action version: latest (v2.3.1)
• OS, where your action is running (windows, linux): linux
• yaml file here: https://pastebin.com/2KWQAA1B (see the coverage-report item)

Ran into similar troubles, but it just looks like it's a change in whatever the defacto cached node version was on the GitHub runners. Fixed by just being explicit about what node version should be used:

name: 'Jest Coverage Report'
on:
    pull_request:
        branches:
            - main
   
jobs:
    coverage:
        runs-on: ubuntu-latest
        steps:
            - uses: actions/checkout@v3
            - uses: actions/setup-node@v2
              with:
                node-version: 'lts/hydrogen'
                cache: 'npm'
            - uses: ArtiomTr/jest-coverage-report-action@v2
              with:
                test-script: npm run test -- --ci
