I've just double checked the getting started guide and it's working just fine here.

This issue would be caused by the client not being configured correctly. Did you remember to add the Root URL for the myclient?

I can't see what I am missing

Could you send a screenshot instead of video please?

I see it's missing the redirect uri, which is needed. When you create a new client and specify a root url during the first step it'll prefill some other urls. However, if you add the root url after the client is created it won't.

Simplest is probably just to create the client and create a new one. Alternatively you can add a redirect uri, should he https://www.keycloak.org/app/

Thank you for the support I got it working 😊

OK, I see.
In v18 there is no longer a field for specifying root_url.

Thus the "Valid redirect URIs" have to be manually specified which is not specified in the getting started guide.

redirect uri, should he https://www.keycloak.org/app/

It wont work without a wildchar: https://www.keycloak.org/app/*

Thank for the support,

There's no Root URL in the preview new admin console, but there is in the default admin console for KC 18. It should work without the '*', but just tried that and it doesn't. So, looks like there might be an issue, probably in keycloak.js as I'm seeing a pretty weird URL in the error message

type=LOGIN_ERROR, realmId=myrealm, clientId=myclient, userId=null, ipAddress=127.0.0.1, error=invalid_redirect_uri, redirect_uri=https://www.keycloak.org/app/#url=http://localhost:8080&realm=myrealm&client=myclient

Got no clue why #url=http://localhost:8080 is appended to the redirect-uri.

Ah, yes. That makes sense.

Thanks for sorting this out for me.
