Problem Connect Cam StreamCamCross.py

Hello, I'm new to the world of Unitree.
I have a Unitree Go1 Pro and I'm trying to access the cameras via Python with the script, I've already changed my IP to 192.168.123.13 and the ports to 9201, 9202, when I get to the heigh part, width = image.shape[:2], it is returning the error that the object is empty.

Is there anything else that needs to be changed?

Thanks
