Why does pyautogui fall off if I run the script via systemctl?

Question

Python

The script uses the pyautogui module and takes screenshots on request. I added it to systemd, ran it, and the output was with an error:

screen

Is it possible to win somehow without changing the module to another one?

Answer 1

There is no ['DISPLAY'' key in os.environ, look for an error in this.
UPD: Try writing os.environ['DISPLAY'] = ':0' in your code
