It seems like $event can also be of type callable; however, parameter $key of array_key_exists() does only seem to accept integer|string, 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
