I wanted to check - some time ago we developed game on cocos2d-JS 3.8 which was working with no issues in Facebook canvas.
Today we experimented with Cocos2d-JS 3.14 version and seems something was changed in core as getting following error in console when trying access game in Facebook canvas. If using direct site link everything works.
Uncaught DOMException: Blocked a frame with origin "https://mygamesite.com" from accessing a cross-origin frame.

Not sure if it is core issue or some part of our code. Is there confirmation that 3.14 version working with Facebook Canvas? It seems like included JS code trying to access something in Facebook Canvas and browser blocking it.
Could you please check with team this issue, I was testing right now hello world project and it doesn't load in Facebook canvas stuck on console error. Also what strange even project generated with cocos2d-x 3.14.1 in console JS showing 3.14.
