试图理解我的GET请求发生了什么。我使用node.js在后端设置了这个。我第一次以为我使用了错误的.env，url，用户名和密码...但是当我检查Postman时，Basic Auth似乎可以毫无问题地获取JSON数据。我是不是用错AXIOS了？
下面是我的GET请求：

let customers;
try {
    let user_res = await axios({
        method: "GET",
        url: "api._____.com/customers",
        auth: {
            username: process.env.USERNAME,
            password: process.env.PASSWORD
        }
    });
    customers = user_res.data;
    console.log(customers);
} catch (err) {
    const error = new HttpError(
        "API failed, please try again.",
        500
    );
    return next(error);
}

错误日志：
