User::getProfile retrieves null when it shouldn't

Describe the bug

I'm trying to get all users in a group and after that getting the users profile.
While this won't work:

1. getting Users as transitiveMembers of a group
   UserCollectionResponse userResult = graphClient.groups() .byGroupId(groupId) .transitiveMembers() .graphUser() .get();
2. iterate over all users
   userResult.getValue().forEach(this::getProfile);
3. call User::getProfile but it returns always null even when profile is existing and permissions are granted.
   private void getProfile(User user) { Profile profile = user.getProfile(); }

It will work when you do this instead of user.getProfile() in step 3:
private void getProfile(User user) { Profile profile = graphClient.users().byUserId(user.getId()).profile().get(); }
This returns the profile for me.

Expected behavior

when calling User::getProfile i expect to get the profile back instead of null.

How to reproduce

1. getting Users as transitiveMembers of a group
   UserCollectionResponse userResult = graphClient.groups() .byGroupId(groupId) .transitiveMembers() .graphUser() .get();
2. iterate over all users
   userResult.getValue().forEach(this::getProfile);
3. call User::getProfile but it returns always null even when profile is existing and permissions are granted.
   private void getProfile(User user) { Profile profile = user.getProfile(); }

Beginne damit, den Ablauf von transitiveMembers() zu reproduzieren, und untersuche User::getProfile() für Benutzer, die von dieser Kette zurückgegeben werden. Vergleiche ihn mit graphClient.users().byUserId(user.getId()).profile().get(); abgeschlossen ist die Aufgabe, wenn der direkte Zugriff auf das User-Profil im gemeldeten Szenario das vorhandene Profil zurückgibt.
