CH2 example doesn't display the buttons after logging in

[scottsdrv]

After successfully logging in to the frontend application included in the CH2 example application, all I see is a blank page. I've tried this in both Chrome and Safari, and the same results are the same.

Looking at index.html, I would expect to see:

• Logout button
• Show ID Token button
• Show Access Token button
• Refresh button
• Invoke Service button

Am I missing something?

I was able to get around the issue by changing the "Web origins" config in the 'myclient' client to either a plus sign "+" or an asterisk "*".

I too just see a blank screen after login, but changing web origins to * does not help.
I am user docker image quay.io/keycloak/keycloak:22.0.3

Adding "*" to Web Origins helped me.

Just remove a trailing slash after a port number in the "Web origins" URL to fix this problem. Here's what is written in a browser's console output:
localhost/:1 Access to XMLHttpRequest at 'http://localhost:8080/realms/myrealm/protocol/openid-connect/token' from origin 'http://localhost:8000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.
