An error occurred while trying to read the map file

[eliw00d]

I'm trying to get this to work with Playwright + Electron and have the following:

test.beforeAll(async () => {
    page = await electronApp.firstWindow()
    await page.coverage.startJSCoverage()
})

test.afterAll(async () => {
    const coverage = await page.coverage.stopJSCoverage()
    for (const entry of coverage) {
      const converter = v8toIstanbul('', 0, { source: entry.source! })
      await converter.load()
      converter.applyCoverage(entry.functions)
      console.log(JSON.stringify(converter.toIstanbul()))
    }
})

My project is set up with Electron Forge, so it uses Webpack and TypeScript.

It works for one test but another throws the following error:

Error: An error occurred while trying to read the map file at /Users/eliw00d/projects/myProject/index.js.map

Which points to: https://github.com/istanbuljs/v8-to-istanbul/blob/master/lib/v8-to-istanbul.js#L52

I have "sourceMap": true in my tsconfig.json so I'm not sure what's going on here. Any thoughts?

I have the same problem. Any idea on how to solve? Thanks!
