API issues

[Soala7]

I wrote a javascript code that connects my user on my website to generate random quotes based on what they would like but it's not working here is the code

Script. js
async function getQuote() {
const category = document.getElementById("category").textContent || "success";
const quoteText = document.getElementById("quote");
const quoteAuthor = document.getElementById("author");

quoteText.textContent = "Loading...";
quoteAuthor.textContent = "";

try {
const res = await fetch('https://quote-generator-api-six.vercel.app/' + category);
const data = await res.json();

quoteText.textContent = `"${data.content}"`;
quoteAuthor.textContent = "– " + data.author;

} catch (err) {
quoteText.textContent = "Could not fetch quote. Please try again.";
quoteAuthor.textContent = "";
console.error(err);
}
}

// Load first quote
getQuote();

// Update every 10 seconds
setInterval(getQuote, 10000);
