pyautogui throws me error message. How can I fix my code?

Question

It gives me error message like below. How can I fix this?

Traceback (most recent call last):
  File "c:UsersjayjeotempCodeRunnerFile.py", line 3, in <module>
    x, y = pyautogui.locateCenterOnScreen('yellow.png', confidence=0.8)
TypeError: cannot unpack non-iterable NoneType object

I made a code as below. I think that if x.size == 0: is the problem.

import pyautogui

x, y = pyautogui.locateCenterOnScreen('yellow.png', confidence=0.8)
if x.size == 0:
    print("Not Detected")
    pyautogui.click(1280,720)
else:
    print("Detected")
    pyautogui.click(x, y)

When I do print(x), I get the same error message.

This was changed in version 0.9.41. After that point, if the window is not found, it raises an exception. Before that point, it returns None. So, you need:

pt = pyautogui.locateCenterOnScreen('yellow.png', confidence=0.8)
if not pt:
    print("Not Detected")
    pyautogui.click(1280,720)
else:
    x, y = pt
    print("Detected")
    pyautogui.click(x, y)

If you upgrade, you will have to add exception handling for this case.
