Not reading my code coverage report files

[ChrisMBarr]

I have a monorepo with a one NestJS server project using Jest for tests, and the others are front-end Angular apps using Jasmine/Karma for testing. My Jest tests work perfectly, and I am able to execute my Jasmine tests and generate the JUint and coverage JSON files, but I get this error

File read successfully "./webapp1/coverage/webapp1/coverage-final.json"
Error: Parse summary report. Cannot read properties of undefined (reading 'lines')

Please note that I am well aware that this project is specifically about Jest and not Jasmine/Karma, however it seems as though both frameworks can generate the same reporting files, so I'm not sure it matters too much.

Here is my karma.conf.js file for one of the web apps

module.exports = function (config) {
  config.set({
    basePath: '',
    frameworks: ['jasmine', '@angular-devkit/build-angular'],
    plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-jasmine-html-reporter'),
      require('karma-junit-reporter'),
      require('karma-coverage'),
      require('@angular-devkit/build-angular/plugins/karma'),
    ],
    reporters: ['progress', 'kjhtml'],
    browsers: ['Chrome', 'ChromeHeadless'],
    client: {
      jasmine: { },
      clearContext: false, // leave Jasmine Spec Runner output visible in browser
    },
    jasmineHtmlReporter: {
      suppressAll: true, // removes the duplicated traces
    },
    junitReporter: {
      useBrowserName: false,
      outputFile: 'junit.xml',
    },
    coverageReporter: {
      dir: require('path').join(__dirname, './coverage/webapp1'),
      subdir: '.',
      reporters: [{ type: 'html' }, { type: 'text-summary' }, { type: 'json' }],
    },
    failOnEmptyTestSuite: false,
    port: 9876,
    colors: true,
    logLevel: config.LOG_INFO,
    autoWatch: true,
    singleRun: false,
    restartOnFileChange: true,
  });
};

And then the web apps are set up with this script in package.json
"test-coverage-report": "ng test --no-watch --code-coverage --reporters=junit --browsers=ChromeHeadless"

When I run that script locally, it generates a junit.xml file and it generates a coverage-file.json file, which look correct to me

And then on GitHub I run all my tests like this

 - name: 🧪 Unit Tests - Server
    working-directory: server
    run: npx jest --coverage --coverageReporters=text --coverageReporters=json-summary --reporters=jest-junit --reporters=github-actions

  - name: 🧪 Unit Tests - webapp1
    working-directory: webapp1
    run: npm run test-coverage-report

  - name: 🧪 Unit Tests - webapp2
    working-directory: webapp2
    run: npm run test-coverage-report

  - name: 🧪 Unit Test Reporter

When I run this on github, this is what is produced:

Found previous comment, updating

Since the output says it can read the file, but then it cannot read a lines property, my suspicion is that it it trying to read the coverageThreshhold.global.lines property of the jest.config.js file, which does not exist in these web app projects. Is there some way to tell it to read these simple percentage properties from a different file? Here is how karma sets those up: https://github.com/karma-runner/karma-coverage/blob/master/docs/configuration.md#check

I haven't worked with karma before, so it's hard to say if it should work or no.
Need to look at the files that karma provide and compare their format to the jest format file.

Can you provide some example files that karma generates?
If you can't provide files, which is fine, you can compare the files that you have with the current files format that this action is working:
examples

• junit.xml
• coverage-summary.json
• coverage-final.json
