Are you trying to figure out why the Google oAuth popup on your website is blank?
When dealing with Google OAuth it is crucial to ensure that both versions of a domain (with and without “www”) are listed as “Authorized JavaScript Origins” in the Google Cloud credentials. This ensures that Google’s authentication service can recognise and accept requests from both variations of your domain. Alternatively, make sure that your website does a redirect to the expected domain version (i.e. either with or without the www). Failure to do so results in blank sign-in popups.
