Trying to use AWS lambda to send data to a dynamodb table

Question

console.log('starting function');

var dynamodb = new AWS.DynamoDB();
var AWS = require('aws-sdk');

exports.handler = function (e, ctx, callback) {
    var params = {
        Item: {
            "Name": {
                S: "Dalton Warden"
            },
            "PhoneNumber": {
                S: "796-353-1416",
            }
        },
        ReturnConsumedCapacity: "TOTAL",
        TableName: "CustomerInfo"
    };


    dynamodb.putItem(params, function (err, data) {
        if (err) console.log(err, err.stack); // an error occurred
        else console.log(data);               // successful response
    });
};

I'm pretty new to lambda and dynamoDB but i'm trying to send data to a table I have set up. I've been through amazon's documentation and looked for similar instances on this site and The formatting looks like it would return the correct JSON but I'm still having trouble. The error I'm getting is Cannot read property 'DynamoDB' of undefined".

Please change the order of the below statements as mentioned below (first AWS and then dynamodb).

var AWS = require('aws-sdk');
var dynamodb = new AWS.DynamoDB();

Thanks i'm no longer getting an error but my response is null.

That's because putItem API doesn't return any value. In other words, the variable "data" should be null for put item. Please check the table whether it has the inserted item.
