GCS Callback error ohif v3

I’ve mentioned all things below

I’ve added OAuth 2.0 Client ID to the google.js file of OHIF app file and change the environment variable foe APP_CONFIG to google.js

When i run the app it’s showing an error below. I don’t know how to manage callback for GCS callback and it’s state & access_token

Also, I’ve hosted the OHIF viewer into the FireBASE hosting and it’s same problem occurred.

Please anyone share the solution.

Best Regards!
