thread.rb: terminated with exception

**Describe the bug** My script crashes after a Ferrum thread throws an exception. First I get this: #<Thread:0x0000027cd26b3900 C:/Users/User/.gem/ruby/3.2.0/gems/ferrum-0.15/lib/ferrum/utils/thread.rb:9 run> terminated with exception (report_on_exception is true): C:/Users/User/.gem/ruby/3.2.0/gems/ferrum-0.15/lib/ferrum/network.rb:376:inblock in subscribe_request_will_be_sent': undefined method `response=' for nil:NilClass (NoMethodError)

      previous_exchange.response = response

undefined methodinclude?' for nil:NilClass (NoMethodError)

                            if traffic.url.include?(CGI.escape(x))
                                          ^^^^^^^^^

from my code where traffic is from page.network.traffic.each { |traffic| .....}

Obviously my traffic.url is nil but somehow I don't believe this should be possible, I guess Chrome would not even create a request if the url is missing.

To Reproduce Sorry but can't imagine how to provide a meaningful context... I'll try to describe: 1. sending Chrome to a url. 2. filling a form which triggers a xhr 3. analyzing network traffic to obtain the specific xhr in question by filtering the array of Exchanges page.network.traffic on their url property.

Expected behavior

Additional context I don't know if this has something to do with the above (another nil object), but look at what I get in irb:

irb(main):062:0> browser = Ferrum::Browser.new(url: 'https://github.com/rubycdp/ferrum#frames') C:/Users/User/.gem/ruby/3.2.0/gems/ferrum-0.15/lib/ferrum/browser/process.rb:177:inws_url=': undefined method `host' for nil:NilClass (NoMethodError)

    @host = @ws_url.host
