How to obtain OAUTH for our app users?

Chat and IRC

We are already doing the dance, and every thing works, except we don’t get back an OAuth token. We get an “access code” that doesn’t work, but the codes we get from the tmi OAuth generator DO work. Here is the code

let responseStr = “https://id.twitch.tv/oauth2/authorize?response_type=code&token+id_token&client_id=” + twitchCltId + “&redirect_uri=” + redirectUri + “&scope=chat_login+viewing_activity_read+openid+user:read:email+bits:read&state=” + randState;

// At the redirect uri:
if (req.query.state == randState && req.query.code) {
const code = req.query.code;
request({
uri: “https://id.twitch.tv/oauth2/token?client_id=” + twitchCltId + “&client_secret=” + twitchSecret + “&grant_type=authorization_code&redirect_uri=” + redirectUri + “&code=” + req.query.code,
method: “POST”,
timeout: 10000,
followRedirect: true,
maxRedirects: 10
}, function(error, response, body) {
// Todo: Validate the response id_token

            var jsonResponse = JSON.parse(body);
            var idToken = jsonResponse["id_token"];
            var accessToken = jsonResponse["access_token"];
            var refreshToken = jsonResponse["refresh_token"];

            var postUrl = "https://api.twitch.tv/helix/users";
            var options = {
                method: 'GET',
                url: postUrl,
                timeout: 10000,
                headers: {
                    "Authorization": "Bearer ".concat(accessToken)
                }
            };
            request(options, function(error,response,body){
                // Store in the db
                console.log("res: ", response);
                if(error) {
                    console.log("error in request", error);
                    res.send(error);
                    return
                }
                var jsonResponse = JSON.parse(body);
                var userData = jsonResponse.data[0];
