Protocol error (Target.setAutoAttach): Session closed. Most likely the iframe has been closed. (Puppeteer::CDPSession::Error)

[akichim21]

Step To Reproduce / Observed behavior

It will run to the end, although an error will occur.
Comment out browser.disconnect and the error disappears
Is it because the part doing parallel processing is not terminating at the time of disconnect?

connect do |browser|
xxx
end
Is same.

  class Scraping
    def execute
      browser = Puppeteer.connect(
        browser_ws_endpoint: "ws://docker.for.mac.localhost:9222/devtools/browser/xxxx",
        // Error also occurs in the following
        // browser_ws_endpoint: "ws://127.0.0.1:9222/devtools/browser/xxx"
      )
      browser.disconnect
      p 1111
    end
  end

bundle exec rails c
Scraping.new.execute
