when i click save and deploy my code dus not actualy safe

Hello, I am new to using Cloudflare Workers and have been using Pages for a few months now. I am trying to create a very basic authentication system for my page. However, when I click deploy on Cloudflare, the button just turns blue, and I don't receive any error codes or feedback. I believe I might be doing something wrong, so any help or guidance would be greatly appreciated. Thank you for your assistance.
