That’s the whole problem of marrying GR with QM. Among the usual forces, gravitation does act like an anomaly (except with string theory) It is not quite a force but a curvature of space, neeeding a quatization of space-time, and that has not been found, despite impressive attempts (string theory, loop gravity, DeWitt-Wheeler equations, among others).
