Return error when redirect to popUp window fails while getting token

[shruthi1994]

Describe the feature request?

Opening the redirectUrl in the popUp doesn't return any error when it fails

okta-auth-js/lib/oidc/getToken.ts

Line 166 in a6c21cc

popupWindow.location.assign(requestUrl);

For example when the redirectUrl fails because of 429 status code I would like to receive a http status code. Currently if it fails all I get is 'Unable to parse OAuth flow response' which doesn't really explain what's the exact reason.

I believe it's not currently possible.
Popup window should have same origin as opener to allow reading HTML content of opened window.
Communication between your app (okta-auth-js SDK) and popup window is implemented with cross-window events and such messages are not produced in case of HTTP 429, 404, 400 or other errors.
