Karma can't stay connected to Chrome 73

See original GitHub issue

My machine updated Chrome to 73 today. Following that, I am getting the following error after my tests have run the first time, whilst waiting for file changes:

25 03 2019 11:21:23.525:WARN [HeadlessChrome 73.0.3683 (Mac OS X 10.13.6)]: Disconnected (0 times)reconnect failed before timeout of 10000ms (transport close)
HeadlessChrome 73.0.3683 (Mac OS X 10.13.6) ERROR
  Disconnectedreconnect failed before timeout of 10000ms (transport close)

If I make further changes to the file, I get the following warning:

25 03 2019 11:24:29.076:WARN [karma]: No captured browser, open http://localhost:9876/

If I open http://localhost:9876/ I see the Karma logo flash up, the tests run again, then this message:

25 03 2019 11:24:56.196:WARN [Chrome 73.0.3683 (Mac OS X 10.13.6)]: Disconnected (0 times)Client disconnected from CONNECTED state (transport error)
Chrome 73.0.3683 (Mac OS X 10.13.6) ERROR
  DisconnectedClient disconnected from CONNECTED state (transport error)

Followed by “Aw, snap!” in the browser window. Things I’ve tried for a fix:

Terminal restart
Killing all chrome instances before starting
Restarting the machine
Reinstalling all node modules
Updating karma and karma-chrome-launcher

Nothing has worked.

Thanks.

I’ve got it fixed by upgrading the Puppeteer and this downloaded a newer version of Chromium.

This thread did send me in the right direction.

Just had a similar connection timeout issue. Updated puppeteer version also worked for me.
