Error: Protocol error (Fetch.continueWithAuth): Page closed. about cli HOT 2 CLOSED

Hey @yuiseki!

The Page closed part of the error suggests that the page was closed in the middle of performing that protocol method (the Fetch.continueWithAuth method). The page could have closed for various reasons, but Fetch.continueWithAuth is only called when the requested asset requires authentication. It is called with the discovery.authorization option's username and password, which get treated as basic authentication.

You mentioned setting cookies using Puppeteer's page.setCookie method. Are you also providing the same cookies via Percy's cookies config file option? You could also provide the discovery.authorization option I mentioned. Here are the docs for both of these options: https://docs.percy.io/docs/cli-configuration#discovery

The discovery.authorization option can also be provided on a per-snapshot basis with snapshot options: https://docs.percy.io/docs/cli-configuration#per-snapshot-configuration

The cookies option is fairly new, and isn't well documented quite yet (we're working on better docs soon). If you need to set simple cookies, you can do so like this:

# .percy.yml
version: 2
discovery:
  cookies:
    my-cookie: 'cookie-value'
    other-cookie: 'foobar'

If you need other cookie parameters, you can provide an array similar to Puppeteer's page.setCookie method:

# .percy.yml
version: 2
discovery:
  cookies:
    - name: 'my-cookie'
      value: 'cookie-value'
      url: 'http://url-for-cookie'
      # ... other cookie params
    - name: 'other-cookie'
      value: 'foobar'
      # ... etc

from cli.

Going to close this one up but feel free to keep commenting 😃
