[Python] TypeError: handle_connection() missing 1 required positional argument: 'path'

I have the following code.

server.py:

import asyncio
import websockets
from websockets.exceptions import ConnectionClosedError

async def handle_connection(websocket, path):
print("[+] Client connected.")
try:
async for message in websocket:
print(f"[*] Message received: {message}")
response = f"Server Echo: {message}"
await websocket.send(response) # Send response to client
except ConnectionClosedError as e:
print(f"[-] Connection closed by client: {e}")
except Exception as e:
print(f"[!] Unexpected error: {e}")

async def main():
server = await websockets.serve(handle_connection, "0.0.0.0", 9000)
print("[+] WebSocket server started on port 9000...")
await server.wait_closed()

if __name__ == "__main__":
asyncio.run(main())


client.py:

import asyncio
import websockets
from websockets.exceptions import ConnectionClosedError, InvalidURI, InvalidHandshake

async def test_websocket():
uri = "ws://localhost:9000" # Make sure the port matches the server
try:
async with websockets.connect(uri) as websocket:
print("[+] Connected to WebSocket Server")

try:
message = "Hello Server!"
print(f"[*] Sending: {message}")
await websocket.send(message)

response = await websocket.recv()
print(f"[+] Server Response: {response}")
except ConnectionClosedError as e:
print(f"[!] Connection Error: {e}")
except (InvalidURI, InvalidHandshake) as e:
print(f"[!] Error connecting to server: {e}")
except Exception as e:
print(f"[!] Unexpected error: {e}")

asyncio.run(test_websocket())


This is the error when I'm trying to run client.py:

PS C:\Users\ruben\OneDrive\Ambiente de Trabalho\Honeypot> python client.py

^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: handle_connection() missing 1 required positional argument: 'path'


I already killed the process in the port 9000 and changed the port, assuming that is the problem, but I'm wrong. How can I fix this?
