Hi @szaher,

Please fill in the template before raising an issue in the future. This helps us to narrow down the issue and diagnose your problem more quickly.

As for HTTP trigger, the function annotation indicate that you need to return an HttpResponse object instead of a None. If you expect your http client receive no content, you should use return func.HttpResponse("", status_code=200) instead.

“You’ve got to return something. It says it in the function’s declaration with the arrow operator… it’s that obvious! how could you not see that you dummy?” is what I said to myself after discovering the mistake x) thanks @Hazhzeng https://github.com/Hazhzeng 🙏

@thegamebegins25 https://github.com/thegamebegins25 you are not returning anything too, hence, the NoneType return error. What you are doing actually is returning a value from the function set, that you are calling in main, without using that value, so in main, you are returning nothing. Add a return in front of set.
