/usr/local/lib/python3.6/dist-packages/chromewhip/helpers.py As you can see in debugger there is no frameId and loaderId in params and LifecycleEventEvent constructor needs it!

Is that an error in chromewhip or i understand something wrong? This error also arrised when using docker and http api.

@andreymeretsky I’ve been able to recreate error in my Docker container (works fine locally under MacOS), will let you know how I go.

I think the Docker Error might be that you never start Chrome. This causes it to time out while connecting to the remote debug port. This is fixed by you having Chrome running locally with --remote-debug-port=9222 as per the readme.
