[keycloak-user] "Invalid parameter: redirect_uri"

[Paul Blair]

I should mention that this happens whether or not I have https://[apimanLoadBalancer]<https://[apimanLoadBalancer]/apimanui> in the Root URL field for the Apimanui client, or whether or not I have https://[apimanLoadBalancer]/apimanui/* in the Valid Redirect URIs, or both. However, if they are present I no longer see the DEBUG line "replacing relative valid redirect with..."; I only see the WARN message with the failure.

Also, it appears that the URL encoding is a non-issue; at least, I see the URLs encoded properly in the browser URL bar even if the "inspect" formats them with slashes and colons.

Subject: [keycloak-user] "Invalid parameter: redirect_uri"

I am using Keycloak with the apiman API manager. Both are on AWS and are behind Elastic Load Balancers (Keycloak is clustered using JDBC_PING). When I request the apiman admin UI page (https://[apimanLoadBalancer]/apimanui), I get redirected to the following URL:

    https://[KeycloakLoadBalancer]/auth/realms/apiman/protocol/openid-connect/auth?response_type=code&client_id=apimanui&redirect_uri=https://[apimanLoadBalancer]/apimanui/index.html&state=3/c48eec70-0fe9-44bf-9802-a351353f7600&login=true

Keycloak then displays the error "We're Sorry... Invalid parameter: redirect_uri"

In the Keycloak log I see:

    DEBUG [org.keycloak.protocol.oidc.utils.RedirectUtils] (default task-7) replacing relative valid redirect with: https://[KeycloakLoadBalancer]/apimanui/*
    WARN  [org.keycloak.events] (default task-7) type=LOGIN_ERROR, realmId=apiman, clientId=apimanui, userId=null, ipAddress=[IP], error=invalid_redirect_uri, response_type=code, redirect_uri=https://[apimanLoadBalancer]/apimanui/index.html, response_mode=query

This looks to me as though Keycloak thinks that the redirect URI is a relative path. I also notice that the query string parameters for redirect_uri are not URL encoded by apiman. Would this be the source of the problem?
