[keycloak-user] Incorrect redirect_uri in Authorization Code Flow

Hi, I'm trying to setup a public client in Keycloak 6.0.1 to make an Authorization Code Flow to work but it fails on the post after the redirect. 1. I've create the following client in the realm "test": client id => keycloak-java-form-example enabled => on client protocol => openid-connect access type => public standard flow enabled => on valid redirect uris => http://localhost:9090/* 2. Manually created a user. 3. Created a simple app. When you go to http://localhost:9090/ it redirects to: https://keycloak.server:8443/auth/realms/test/protocol/openid-connect/aut... 4. I log in in the form and get the response on the endpoint http://localhost:9090/cb with a code (for example: 337f8ec8-dbdd-4965-b538-e5a4fbfff6b4.4cb543a8-1585-4bd0-b174-031288cf3032.cf57276c-98a9-48d3-b460-c678af3f8eb2). 5. I make the following POST request: POST https://keycloak.server:8443/auth/realms/test/protocol/openid-connect/token grant_type=authorization_code client_id=keycloak-java-form-example code=337f8ec8-dbdd-4965-b538-e5a4fbfff6b4.4cb543a8-1585-4bd0-b174-031288cf3032.cf57276c-98a9-48d3-b460-c678af3f8eb2 redirect_uri=http%3A%2F%2Flocalhost%3A9090%2Fcb The response is: 400 {"error":"invalid_grant","error_description":"Incorrect redirect_uri"} I'm not sure what I'm missing. Thanks
