Im trying to upload my programming language project with pypi, and i have an error while running py -m twine upload --repository testpypi dist/*

i get an error in cmd, saying: myemail is an invalid value for Author-email. Error: Use a valid email address

i've tried almost everything, and ive read every documentation, but i cant get it to work

(it isn't a problem with the setup.cfg file, because when i changed it, a different email popped up in the error)
