CS50P unit testing problem set 5(back to bank) whereby testing manually works but the check function of cs50p doesnt check code

i am doing a problem set exercise where i am suppose to test my code that i had written before

i have a problem where by check50 does not check my code and it returns an error but when i manually check "pytest" it works as it is . the image below shows my code and my terminal.screenshot of code and terminal

i tried removing my main function to see if that is causing the issue but it still as it is
