r/Netlify

hey yall, so whenever i try to deploy my ai website when hosting on vercel, it keeps saying “404 not_found” i also tried it on netlify and it says the same thing. on lovable, im able to access the website and interact with it. when i publish it, the link also works and stuff. but the second i wanna host it, it doesnt work. i connect github and lovable together and then i upload my github repo into vercel/netlify, then it says “404 not found” so idk what im doing wrong, maybe im missing a step? but everything works until i wanna actually host the website online. i need help with this since im been trying for about 2 days now and i still dont understand. thank you.
