AWS Lambda: Unable to import module

Question

please forgive me, I am totally new at Lambda and Node.

I am trying to replicate this git to order a pizza using an AWS IoT button.

My current code is:

var pizzapi = require('dominos');

var myStore = new pizzapi.Store(
    {
        ID: 'Example'
    }
);

var myAddress = new pizzapi.Address(
        {
            Street: 'Example',
            City: 'Example',
            Region: 'Example',
            PostalCode: 'Example'
        }
    );

var myCustomer = new pizzapi.Customer(
    {
        firstName: 'Example',
        lastName: 'Example',
        address: myAddress,
        phone: 'Example',
        email: '[email protected]'
    }
);

var order = new pizzapi.Order(
    {
        customer: myCustomer,
        storeID: myStore.ID
    }
);

var cardNumber='Example';
var cardInfo = new order.PaymentObject();
cardInfo.Amount = order.Amounts.Customer;
cardInfo.Number = cardNumber;
cardInfo.CardType = order.validateCC(cardNumber);
cardInfo.Expiration = 'Example';
cardInfo.SecurityCode = 'Example';
cardInfo.PostalCode = 'Example';

order.Payments.push(cardInfo);

function orderDominos(event, context) {
  var clickType = event.clickType;
  switch(clickType.toLowerCase()) {
    case "single": {
      order.addItem(
          new pizzapi.Item(
              {
                  code: 'P_14SCREEN',
                  options: {},
                  quantity: 1
              }
          )
      );
      break;
    }
    case "double": {
        order.addItem(
          new pizzapi.Item(
              {
                  code: 'P_14SCREEN',
                  options: {},
                  quantity: 1
              }
          )
      );
      break;
    }
    case "long": {
        order.addItem(
          new pizzapi.Item(
              {
                  code: 'P_14SCREEN',
                  options: {},
                  quantity: 1
              }
          )
      );
      break;
    }
  }
  order.validate(
      function(result) {
          console.log("Order is Validated");
      }
  );
  order.price(
      function(result) {
            console.log("Order is Priced");
      }
  );
  order.place(
      function(result) {
          console.log("Price is", result.result.Order.Amounts, "\nEstimated Wait Time",result.result.Order.EstimatedWaitMinutes, "minutes");
          console.log("Order placed!");
          context.succeed(event);
      }
  );
}

exports.handler = orderDominos;

The file structure is:

• orderDominos.js
• node_modules/dominos

I zipped the files, uploaded to Lambda, and pointed the header to "index.handler"

What am I doing wrong?

Edit: The error

Answer 1

In my case, i mentioned Handler as index.handler but my root filename is app.js. Changing this to index.js worked.

Also make sure the zip file has your index.js, node_modules and package.json directly.

Should be:

zip file --> index.js
             package.json
             node_modules

Not

zip file --> some_folder_name --> index.js
                                  package.json
                                  node_modules

Answer 2

It was a permission issue for me, after I changed the permissions for the 'node_modules' folder to 777, zipped and uploaded it, it worked.
