ReferenceError: sessionID is not defined

[sscaetite]

I had this issue when run the basic code:

ReferenceError: sessionID is not defined at Instagram.auth.then (C:\Users\samuc\projetos\instabot\app.js:25:21) at process._tickCallback (internal/process/next_tick.js:68:7)

My complete code:

const express = require('express');
const app = express();

let Instagram = require('instagram-nodejs-without-api');
Instagram = new Instagram();

let idOfSession = "Random, only for tests";
let csrfTokenOfSession = "Random, only for tests";

Instagram.getCsrfToken()
    .then((csrf) =>
    {
        Instagram.csrfToken = csrf;
        csrfTokenDaSessao = csrf;
        console.log(csrf);
        console.log(csrfTokenOfSession);
    })
    .then( () =>
    {

        return Instagram.auth('correctUser', 'correctPass')
            .then( (sessionId) =>
            {
                    Instagram.sessionId = sessionId
                    idDaSessao = sessionID;
                    console.log(sessionId);
                    console.log(idOfSession);
            });
    }) 
.catch(console.error);

app.listen(3000, () => {
    console.log("Running at port 3000")
});

syntax error. It should be sessionId, not sessionID
