    Sometimes it’s working because the data is not deleted in that case it works. And when data is deleted and you are redirecting again that page then an error will throw as Call to a member function delete() on null.

    To ignore this value you have to simply create a list view. when you are redirecting to the list view which contains all data which are not deleted

    First, you need check if there is a record with that ID before trying delete it.

    The best way to do it is typing the param.

    In Controller:

    public function destroy(Pegawai $pegawai)
{
    $pegawai->delete();

    return redirect()->route('pegawai.index')->with(['success'=> 'Item Berhasil Dihapus']);
}

    In the route file you need change the param name from $id to $pegawai.

    Laravel will check if the ID is valid before enter into the function.
