I made a troll-like Vercel app. It's a 'yes or no' question. It asks "Do you wanna se my dog?". If yes, then my dog appears with a woof audio, if your answer is no, you get jumpscared. I made it out of fun, a simple code in HTML, CSS and plain JavaScript. But for some reason, when I deployed it using Vercel, it doesn't show any dog picture or jumpscare video, so it really messed up my project. How do I fix it?
