It seems like $this->callable can also be of type null; however, parameter $callback of call_user_func_array() does only seem to accept callable, maybe add an additional type check?
                                                                                                                                                                                           (

 If this is a false-positive, you can also ignore this issue in your code via the ignore-type   annotation
