It seems like $bytes can also be of type false; however, parameter $var of count() does only seem to accept Countable|array, maybe add an additional type check?

It seems like $bytes can also be of type false; however, parameter $array of array_slice() does only seem to accept array, 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
