Reproducing the issue All of the error messages are like the following, but sometimes it's k.get, j.get, etc.

TypeError: Cannot read property 'get' of undefined
arguments: [{"message":"Cannot read property 'get' of undefined","name":"TypeError","stack":"TypeError: Cannot read property 'get' of undefined\n    at Array.<anonymous> (https://www.gstatic.com/recaptcha/releases/bfvuz6tShG5aoZp4K4zPVf5t/recaptcha__zh_tw.js:106:312)\n    at https://www.gstatic.com/recaptcha/releases/bfvuz6tShG5aoZp4K4zPVf5t/recaptcha__zh_tw.js:215:83\n    at t.<anonymous>

Uncaught TypeError: Cannot read property 'get' of undefined

For IE11

recaptcha__en.js (168,31)

I try CTRL + F5 for few times and this error is gone.

For more infomation, I implement v3 and V2 invisible in same page, load js like this
