This is what I see in the console when my custom widget is displayed on my login page. Then when I try to sign in with google:
a new window pops up, and when I look at the URL I notice the responseMode has become okta_post_message. When I change this value manually to fragment and try it, I see that I am successfully getting the id_token and state passed to me in the URL.
Am I missing something to get this to work?
