Browser did not produce websocket

[Hanaffi]

Hello,
We are getting the mentioned error on our CI when we try to adapt Cuprite.
Ferrum::ProcessTimeoutError: Browser did not produce websocket url within 10 second

I don't know why does it say 10 seconds even though Im passing timeout as 300 !

 Capybara.register_driver(:cuprite) do |app|
  Capybara::Cuprite::Driver.new(
      app,
      js_errors: true,
      headless: %w[0 false].exclude?(ENV["HEADLESS"]),
      slowmo: ENV["SLOWMO"]&.to_f,
      process_timeout: 300,
      timeout: 300,
      browser_options: { "no-sandbox" => true } 
    )
end

Please help, thanks 🙏

Try to set through ENV variable in their CI they are passing those values:

    env:
      FERRUM_PROCESS_TIMEOUT: 25
      FERRUM_DEFAULT_TIMEOUT: 15

@Hanaffi most likely you are initializing somewhere another instance of cuprite + ferrum with default settings. It's hard to figure out as it purely depends on your environment. Try also setting ENV vars @navidemad provided and check if you have enough memory on CI because this issue is also an early sign of not sufficient memory 10s is more than enough to start Chrome unless it gets OOM killed or CPU is saturated, both are bad.
