Problem:
When implementing Google reCAPTCHA, you might encounter the following error:
Uncaught DOMException: Failed to read a named property 'a-9tu39a56hre3' from 'Window': Blocked a frame with origin "https://www.google.com" from accessing a cross-origin frame.
This error occurs because of a conflict between Google's reCAPTCHA and Chrome's security mechanisms. reCAPTCHA's v2 version attempts to access a cross-origin frame placed on your website, but Chrome blocks this access for security reasons.
Proposed Solution 1:
One proposed solution is to attach the reCAPTCHA to the document body instead of your application. This grants access to reCAPTCHA's DOM and allows it to function properly.
Proposed Solution 2:
Another suggestion is to develop your own CAPTCHA system with better code and reduce reliance on Google's products.
Note:
The "cross-origin allowed" setting in Webpack dev server or AWS infrastructure settings does not resolve this issue. The error is caused by a fundamental conflict between reCAPTCHA and Chrome's security features.
