Hi ,
We have two web applications in our SharePoint 2016 farm(e.g. http://abc:40109 and http://abc:50109).
We have to display SharePoint Page(e.g. http://abc:40109/Pages/Feedback.aspx) of web application (http://abc:40109) into another web application in Modal Dialog box(which renders the page in iframe).
The page is display correctly and worked as expected. Moreover ,AllowFraming control is already added.
When page is getting open and looking into console , it is showing below error
init.js?rev=X4eySfc6naagwmlfS0Ythw%3D%3DTAG0:1 Uncaught DOMException: Blocked a frame with origin "http://abc:40109" from accessing a cross-origin frame.

(anonymous) @ init.js?rev=X4eySfc6naagwmlfS0Ythw%3D%3DTAG0:1
The code line in init.js (if(window.parent!=null&&typeof window.parent.SP=="object"&&typeof window.parent.SP.CacheLogger=="object"&&window.parent.location.protocol==window.location.protocol) is trying access parent object.
We have tried different solutions but nothing worked to remove that error. Below are some solutions we tried
1. Adding Custom Headers like X-FrameOptions , Content-Security-Policy , Access-Control-Allow-Origin etc.
2. Configured URL Writing .
3. Setting Allow external iframes in Html Field Security options
Any help will be appreciated.
Thanks
