Hello, this morning my code was working very well but now, i am getting 401 error.

 ![image](https://d2opxh93rbxzdn.cloudfront.net/original/2X/4/482b5e23785629bc77e9074c2058a27651f07a23.png)

This is the code:

```
const callAJAX = (props) => {
    const url = props.url,
        method = props.method || "GET",
        type = props.type || "JSON",
        header = props.header
    ;
    
    return new Promise(waitForResult => {
        const xhttp = new XMLHttpRequest();
        xhttp.onreadystatechange = function() {
            if (this.readyState === 4 && this.status === 200) {
                type === "text" 
                    ? waitForResult(this.response)
                    : waitForResult(JSON.parse(this.response))
                ;
            }
        };
		
        if (method === "GET") {
            xhttp.open("GET", url, true);
            for (const key in props.header) {
                xhttp.setRequestHeader(key, header[key]);
            }
            xhttp.send();
        }
    });
};

const AJAXProps = {
    url: "https://api.twitch.tv/helix/streams?first=20",
    header: {"Client-ID": "cpfxuznsjx64e2k6h58ujmmwtsqr29"}
};

var users = ["esl_csgo"];

var user_login = users.join('&user_login=');

    callAJAX(AJAXProps).then(allUser => {

        AJAXProps.url = `https://api.twitch.tv/helix/streams?user_login=${user_login}`;

        callAJAX(AJAXProps).then(onlineUsers => {
		
		console.log(onlineUsers);
		
		});
    });

```

Thank you
