locateAllOnScreen raises pyscreeze.ImageNotFoundException

[eight04]

>>> list(pyautogui.locateAllOnScreen("test.png"))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\eight04\dev\valkyrie-connect-auto\.venv\Lib\site-packages\pyscreeze\__init__.py", line 257, in _locateAll_opencv

pyscreeze.ImageNotFoundException: Could not locate the image (highest confidence = 0.178)

While locateOnScreen raises pyautogui.ImageNotFoundException correctly:

>>> pyautogui.locateOnScreen("test.png")
Traceback (most recent call last):

pyscreeze.ImageNotFoundException: Could not locate the image (highest confidence = 0.167)

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\eight04\dev\valkyrie-connect-auto\.venv\Lib\site-packages\pyautogui\__init__.py", line 174, in wrapper

pyautogui.ImageNotFoundException

I guess the problem is that locateAll returns a generator, hence you have to wrap its __next__ method to catch the error, or use yield from.
