It seems that there is a problem with resolving custom user meta fields with version 0.3.
I made sure to update my action graphql_register_types resolvers by replacing the legacy \WP_User with \WPGraphQL\Model\User but it seems that the User object cannot get resolved with $user->ID unless it is hardcoded.
Below is a reproduction of the issue (gif)...

@szvest try using $user->userId since $user->ID is the global ID, not the DB int ID now.
Excellent! Works like a charm now. Thanks @CodeProKid.
Thanks @CodeProKid! closing this issue.
ah @szvest beat me to it 馃槃
