Recursive Promises Not Returning

Question

I have a recursive function like so

function missingItemsPromise() {
    return new Promise(resolve => {
        if (missingItems == 0) {
            con         


        

Answer 1

you are missing the return statement inside the else condition

function missingItemsPromise() {
    return new Promise(resolve => {
        if (missingItems == 0) {
            console.log('resolves');
            console.log(products);
            return resolve();
        } else {
            page++;
            url = getUrl(id, page);
            http.get(url, function(xres) {
                xres.setEncoding('utf8');
                xres.on('data', function (xtraBody) {
                    console.log('calling');
                    var xtraJson = JSON.parse(xtraBody);
                    var xtraProducts = xtraJson['products'];
                    products = products.concat(xtraProducts);
                    productsLength = products.length;
                    missingItems = total - productsLength;
                   return  missingItemsPromise(); //this is the line that changes
                });
            });
        } 
    });
};
