@niezbop That's very rare intermittent issue, which is not possible by all means. I couldn't catch it locally but if you could catch it with CUPRITE_DEBUG=true env turned on it would be great, because Chrome should return at least one default target. Looks like race condition in Chrome.

I think I'm gonna close it for now as it doesn't look like an issue in cuprite, though if you catch it especially with debug option again please submit the log file. Thank you!

@route I wonder if you could possibly help me or give some advice. It seems I have a similar issue with a gem is based on the cuprite 0.6.0. And I have some tests where this issue appears regularly. When I run this with CUPRITE_DEBUG=true I have got the following result:
$ CUPRITE_DEBUG=true bundle exec rspec --seed 123 ./spec/browser_crawler_spec.rb
with max_pages option specified

Maybe, I do something wrong, but such errors appear constantly.
If you have time you can take a look at the code here and also take a look at the failed spec file here.
I hope it helps you find a solution.
Please let me know if you have other questions or concerns. Thank you!

I just merged one fix related to this issue, could you try using cuprite from master? Does it resolve the issue?

@route, Thank you for your rapidly answer.
I rerun tests from cuprite (master). However, the previous error is disappeared, but another error has appeared:
>>> {"method":"Target.getTargets","params":{},"id":4}
<<< {"id":4,"result":{"targetInfos":[]}}

What browser version do you use? I've never seen it failing that constantly ;)

I use Chrome with Version 74.0.3729.169 (Official Build) (64-bit). I have seen a capybara issue regarding Chrome 74 (teamcapybara/capybara#2181) and rerun tests with these options: --enable-features=NetworkService,NetworkServiceInProcess, but errors are the same.
