Reading response hangs on Puppeteer.connect after 0.42.0

[ritu1337]

Step To Reproduce / Observed behavior

Works on tag 0.42.0 but doesn't work on any newer:

Puppeteer.connect(browser_ws_endpoint: "ws://...") do |browser|
  page = browser.new_page
  response = page.goto("https://whatismyviewport.com/")
  response.text # hangs indefinitely
  page.screenshot() # also hangs
end

Above example works on the GitHub example URL i.e. page.goto("https://github.com/YusukeIwaki") but not on some other URL's e.g. https://whatismyviewport.com/ or https://www.youtube.com/.

Expected behavior

Doesn't hang on response.text or page.screenshot() when Puppeteer.connect is used.

Environment

ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-linux]

I tried this and it worked.

Puppeteer.connect(browser_ws_endpoint: "wss://chrome.browserless.io?token=#{BROWSERLESS_API_KEY}") do |browser|
  page = browser.new_page
  response = page.goto('https://github.com/YusukeIwaki')
  puts response.text
  page.screenshot(path: 'YusukeIwaki.png')
end

However, after changing the URL of goto as you described, it doesn't work.

  response = page.goto("https://whatismyviewport.com/")

It seems the site whatismyviewport.com uses Service Worker.

@ritu1337 Thank you for your report. puppeteer-ruby 0.45.3 would fix this issue. Could you try it?
