Keycloak version: 26.3.1
I sometimes get "Cannot access delegate without a transaction" error accessing user info. I even tried using KeycloakModelUtils.runJobInTransaction() to ensure I am running in a transaction, only to get this same exception from inside that method.
My code:

KeycloakModelUtils.runJobInTransaction(
        session.getKeycloakSessionFactory(),
        newSession -> {
          var newRealm = newSession.realms().getRealm(session.getContext().getRealm().getId());
          newSession.getContext().setRealm(newRealm);
          var user = newSession.users().getUserById(newRealm, userId);
        });

Error:

So maybe I am doing something fundamentally wrong? what is the recommended method of accessing keycloak info from SPI plugins?
