Are you able at point 3 to run:

curl -i http://127.0.0.1:9222/json/list

If not, there's some TCP connection issue with your phone.

Nope, I am not able to. Any help on how to proceed about it?

MT22067 commented 7 months ago

I did packet capture and could see a few ports connected to 9222 constantly. (exchanging keep-alive messages) I guess forwarding should have worked fine. are you saying that I should capture packets on the mobile device interface?

So the reason is this:

$ chrome-remote-interface inspect -l -w ws://127.0.0.1:9222/devtools/browser
>>> Target.createBrowserContext()
Uncaught ProtocolError: Failed to create browser context.
    at /Users/cyrus/Dropbox/dev/chrome-remote-interface/lib/chrome.js:94:35
    at Chrome._handleMessage (/Users/cyrus/Dropbox/dev/chrome-remote-interface/lib/chrome.js:272:17) {
  request: {
    method: 'Target.createBrowserContext',
    params: undefined,
    sessionId: undefined
  },
  response: { code: -32000, message: 'Failed to create browser context.' }
}

I have no idea why this fails on Chrome for Android, in any case this issue concerns chrome-har-capturer, not this repo.
