I'm trying to make a AHK simple script that connects to my named pipe python script to retrieve real time data. Here is a sample. The named pipe works. When I create a python script to connect to it and print out the sample data, it works, so I know the named pipe is functioning properly. But when I make an AHK script to connect to it, it always says that it failed to connect to it. Any help would be greatly appreciated. Thanks!

print("Waiting for connection...")
win32pipe.ConnectNamedPipe(pipe, None)
print("Connected to pipe.")
try:
while True:
# Sample x, y coordinate data
x = 10

# Convert data to bytes
data = struct.pack('ii', x, y)
# Write data to named pipe
win32file.WriteFile(pipe, data)
print(f"Sent data: x={x}, y={y}")
time.sleep(1)
finally:
win32file.CloseHandle(pipe)
