I think that selenium doesn't like the amount of names in the array. When I reduce my array to 14 names, the code works just fine. When I put in all the names from the teacher notes, the code shows unexpected behavior. My final code looks as followed.

const selenium = require("selenium-webdriver");
const By = selenium.By;

const driver = new selenium.Builder()


const invitees = [
    'Gonzalo Fierro',
    'Shadd Anderson',
    'George Aparece',
    'Shadab Khan',
    'Taron Foxworth',
    'David Riesz',
    'Maicej Torbus',
    'Martin Luckett',
    'Joel Bardsley',
    'Reuben Varzea',
    'Ken Alger',
    'Amrit Pandey',
    'Rafal Rudzinski',
    'Brian Lynch'

const locators = {
    inviteeForm: By.id("registrar"),
    inviteeNameField: By.css("#registrar input[name='name']"),
    toggleNonRespondersVisibility: By.css(".main > div input")

function addInvitee(name) {


function toggleNonRespondersVisibility() {



I see that after i run my code again it doesn't work anymore. Very strange how it randomly works. For mee it helped reducing the amount of names in the array.

It's all working fine with the original names array for me.
