The error message is:

WWW::Mechanize::Chrome decided that the browser wants to send an HTTP request, but then did not find the expected responseReceived event.

This seems to be a bug/unexpected behaviour by Chrome, as the log shows:

            'params' => {
                          'url' => 'https://www.tenthousand.cc/product
+s/interval-short-no-liner?variant=32441933168727',
                          'frameId' => 'F7C8298C7F980A1FF5BAA43B19990B

                        },
            'method' => 'Page.navigatedWithinDocument'
          }

But this event is for a different frame. I can't do it at this time, but as you posted code, maybe I can reproduce the problem using your code and suggest a fix.
