broadcaster ID/userID/Login is a query string parameter, not a header
You should be calling as the URL
http://api.twitch.tv/helix/streams?user_login=imTheSupremeOne
or doing something like
const streamOptions = {
url: GET_STREAM,
method: "GET",
headers: {
'Client-ID': CLIENT_ID,
'Authorization': `Bearer ${accessT}`
},
qs: {
'user_login': `imTheSupremeOne`
}
}
Also worth noting request is deprecated/will not be updated.
