Undefined reading in promise chain

Question

I have a simple employee profile generator app. Everything works just as expected up until the promise for generatePage(employeeData). The console correctly logs employeeData but it is not getting passed to generatePage. Does anyone have insight into why? I have also included a picture of the beginning code for generate-page.js and the "undefined" console error message.

const {writeFile, copyFile} = require('./utils/generate-site.js');
const generatePage = require('./src/page-template.js');
const mockData = [
    {
       // lots of mock data objects here 
    },
]
let employeeData = mockData;

function init() {
    return inquirer.prompt(questions.startQuestions);
}
function getEmployeeData(answers) {
    if (answers.role === 'Engineer') {
        let engineer = new Engineer (
            answers.name,
            answers.id,
            answers.email,
            answers.role
        )
        return getEngineerData(engineer);
    } else if (answers.role === 'Intern') {
        let intern = new Intern (
            answers.name,
            answers.id,
            answers.email,
            answers.role
        )
        return getInternData(intern)
    } else if (answers.role === 'Manager') {
        let manager = new Manager (
            answers.name,
            answers.id,
            answers.email,
            answers.role
        )
        return getManagerData(manager)
    } 
}

function getEngineerData(engineer) {
        return new Promise((resolve) => {
            resolve (
            inquirer.prompt(questions.engineerQuestions)
            .then ((response) => {
                    engineer = {...engineer, ...response};
                    // console.log(engineer)
                    employeeData.push(engineer)
                }
            )
        )
    })
}
function getInternData(intern) {
        return new Promise((resolve) => {
        // same as getEngineerData function
    })
}
function getManagerData(manager) {
       return new Promise((resolve) => {
        // same as getEngineerData function
    })
}
function confirm() {
    return inquirer.prompt(questions.confirmQuestion)
}

function buildTeam() {
    init()
    .then(answers => getEmployeeData(answers))
    .then(confirm)
    .then(response => response.confirmAdd ? buildTeam() : console.log(employeeData))
    .then(employeeData => generatePage(employeeData))
    .then(pageHTML => {
        return writeFile(pageHTML)
    })
    .then (writeFileResponse => {
        console.log(writeFileResponse);
        return copyFile()
    })
    .then(copyFileResponse => {
        console.log(copyFileResponse);
    })
    .catch (err => {
        console.log(err);
    });
}
buildTeam();

Answer 1

console.log returns "undefined" so the solution was to return the employeeData array in the promise chain to pass on.

 .then(response => {
        if (response.confirmAdd) {
            buildTeam()
            return employeeData
        } else {
            return employeeData
        }
    })
