[Regression]: Playwright 1.44 cannot start Electron application with path contains spaces (Windows) about playwright

[mxschmitt]

I'm unfortunately not able to reproduce. I tried version 18 and latest 20, probably related to 5818707.

Which Node.js version are you using on CI? Or are you reproducing it locally?

Could you set the $Env:DEBUG="pw:browser,pw:protocol" env var? This might yield more debug output when launching Electron with Playwright.

It appears to be actually a problem with space characters in the path, which would explain, why this didn't appear on my macOS.

Protocol of the last run:

D:\eigene dateien\devel\web\electron-playwright-issue [master ≡]> $Env:DEBUG="pw:browser,pw:protocol"
D:\eigene dateien\devel\web\electron-playwright-issue [master ≡]> npm test

> [email protected] test
> mocha --timeout 20000



  Sample integration test

  0 passing (21ms)
  2 failing

  1) Sample integration test
       "before all" hook for "opens a window":
     electron.launch: Process failed to launch!
      at async startApp (test\integration.spec.js:10:17)
      at async Context.<anonymous> (test\integration.spec.js:26:39)

  2) Sample integration test
       "after all" hook for "opens a window":
     TypeError: Cannot read properties of null (reading 'close')

  pw:browser [pid=29208] finished temporary directories cleanup

The same project runs on a path without space characters just fine.

So, the regression is at handling space characters in the project's path.
