Hello!  
I tried to use the Twitch API with Javascript. I tried this:

```
const header = {
    headers: {
        'Client-ID': client_id
    }
}
fetch("https://api.twitch.tv/helix/users?login=revedtv", header).then(response => console.log(response))

```

but I only get this error

Can someone please help me?

PS: Sorry for my bad English.
