Bad news.
I’m now on the old kraken APIs and getting the same problem.
I’ve even tried with openid added to the scope and a response type of “code id_token” once again takes the URL fragment route.
The main difference is that openid now seems to work without returning the:
{“status”:400,“message”:“invalid response type: ‘id_token’ required for ‘openid’ scope”}
error however I still get back absolutely no ID Token.
