Hey @Yash_Chaudhari 
- the error you’re seeing is likely related to a known issue on our end and there’s more info here: Blocked script execution in <URL> because the document's frame is sandboxed and the 'allow-scripts' permission is not set.
There is some more information in that thread from some of my colleagues, but my understanding is that this is more of a warning message rather than an error and shouldn’t affect your app’s functionality by itself.
Let me know if I can clarify anything more on my end here - hope this helps!
