Error while trying to run the Client Code - python-3.8

Question

enter image description herePlease I am following a guide to create a Server that responds to the text a Client sends to it but in the reversed order. The Server code runs without any issue but the Client code is not working, its is giving the error message: "OSError:[WinError 10022] An invalid argument was supplied"
Please I need help to resolve this.
Below is the code for both the Server and the Client:
#server.py
import asyncio
import socket
# Get the default "event loop" that we will run
loop = asyncio.get_event_loop()
# notice our new "async" before the function definition
async def server_method():
server = socket.socket()
server.bind(('localhost', 6789))
server.listen(1)
# await for a new client
# The event loop can run other code while we wait here!
client, _ = await loop.sock_accept(server)
# await for some data
data = await loop.sock_recv(client, 1024)
data = data[::-1]
# await for sending the data
await loop.sock_sendall(client, data)
# Close both the Server and Client connections
server.close()
client.close()
if __name__ == '__main__':
# run the loop until "server_method" is complete
loop.run_until_complete(server_method())
#client.py
import asyncio
import socket
loop = asyncio.get_event_loop()
addr = ('localhost', 6789)
async def client_method():
message = b'Hello Server!\n'
client = socket.socket()
client.setblocking(False)
# await to establish a connection
await loop.sock_connect(client, ('localhost', 6789))
# await asyncio.get_event_loop().sock_connect(client, addr)
# await to send the message
print('Sending', message)
await loop.sock_sendall(client, message)
# await to receive a response
response = loop.sock_recv(client, 1024)
print('Server replied', response)
client.close()
if __name__ == '__main__':
loop.run_until_complete(client_method())
