javascript - 未捕获的语法错误：标识符“URL”已被声明

Question

这是我的代码，即使我将名称从 URL 更改为 API_URL，仍然是相同的错误。顺便说一句，我编写的代码只是为了了解 API 的工作原理和了解 Twitter API。在后端，我使用一个变量作为 const URL。那是我认为可能是由于后端和前端的同名错误。这就是为什么我尝试将名称从 URL 更改为 API_URL，但仍然无法正常工作。

const URL = "http://localhost:3000/tweets";


const onEnter = (e) => {
    if(e.key == "Enter"){
        getTwitterData();
    }
}

/**
 * Retrive Twitter Data from API
 */
const getTwitterData = () => {
    
    const query = document.getElementById("user-search-input").value;
    if(!query) return;
    const encodedQuery = encodeURIComponent(query);
    const fullurl =`${URL}?q=${encodedQuery}&count=10`;
    fetch(fullurl).then((response)=>{
        return response.json();
    }).then((data)=>{
        buildTweets(data.statuses);
    })
}

const saveNextPage = (metadata) => {
