Further update about issue is listed below. We exported a realm from 2.2.1 and imported into keycloak 2.3.0.Final instance. When tried to assign group to a newly created user this issue comes but if assign group to migrated user(from 2.2.1 to 2.3.0) it works fine, looks like there is some issue with UserModel.
