@rsimha we are doing a validation check against cdn.ampproject. in our validator code. Travis is complaining about it. Where do we submit an exception for this?

[19:21:16] Found forbidden: "cdn.ampproject." in validator/js/engine/htmlparser-interface.js:271:33

@rsimha I think I got it right in this commit.

There was a problem with this PR as it's missing some code that should have been included. That code is in PR #31373. To keep things simple we're closing this and once that PR is merged will do another rollup.
