[keycloak-user] Missing custom attributes from migrated users

Greetings, I do not see the custom attributes from users created in Realm A, migrated to Realm B. I have configured in Realm A, using it for SSO, a user federation that validates the credentials and fetches user data from a service (via a custom UserStorageProvider), and populates a Keycloak user with name, e-mail, and some corporate attributes like division (setting singleAttributes from UserModel). Then in realm B I have an Identity Provider that points to a Broker in Realm A. In "first login flow" I have a custom Authentication flow, with two execution steps: - Create User If Unique - Automatically Link Brokered Account This allows me to automatically migrate this user to my realm. So login from realm B ends in authentication in realm A, which pulls a user according to our service. Then the process migrates user data to realm B - but as I inspect this user I see e-mail, name (first & last) but I cannot see my custom attributes. Any hints?
