Unable to access dynamodb from nodejs code through lambda - node.js

Question

I have been trying to test this from lambda but unable to proceed.
var Alexa = require("alexa-sdk");
var dynamoDBConfiguration = {
"accessKeyId": "useraccess",
"secretAccessKey": "usersecretkey",
"region": "us-east-1"
};
var AWS = require("aws-sdk");
AWS.config.update(dynamoDBConfiguration);
var promisify = require("es6-promisify");
var dynClient = new AWS.DynamoDB.DocumentClient({"region":"us-east-
1"});
//convert callback style functions to promises
const dbGet = promisify(dynClient.get,dynClient);
const dbPut = promisify(dynClient.put,dynClient);
const dbDelete = promisify(dynClient.delete,dynClient);
var startStateHandlers = (GAME_STATES.STARt, {
"StartGame": function (isNewGame,context) {
const dynamoParams = {
TableName: "Userdata",
Key: {
"UserId":"test"
}
}
dbGet(dynamoParams)
.then(data => {
console.log('Get user succeeded', data);
const userId = data.UserId;
if (userId != null) {
console.log(data.UserName);
}
else {
// no match, add the user
return dbPut(dynamoParams);
}
})
.then(data => {
console.log('Add user succeeded', data);
})
.catch(err => {
console.error(err);
});
this.emit(":tell", speechOutput, speechOutput);
}
});
var handlers = {
"LaunchRequest": function () {
var speechOutput = "hello";
this.emit(":tell", speechOutput, speechOutput);
}
};
var handler = (function () {
function handler(event, context, callback) {
var alexa = Alexa.handler(event, context);
alexa.appId = "appid";
alexa.registerHandlers(handlers, startStateHandlers);
alexa.execute();
}
return handler;
})();
exports.handler = handler;
It doesnt throw any error in the lamda logs and not able to see any log in Cloudwatch. It just executes the other lines of code.
I have attached all permission policy to the user and setup the lamda function as lambda_dynamo.
Unable to understand what is the issue with it.
Appreciate your help.

var dynamoDBConfiguration = {
"accessKeyId": "useraccess",
"secretAccessKey": "usersecretkey",
"region": "us-east-1"
};
var AWS = require("aws-sdk");
// update the AWS.Config global configuration object
AWS.config.update(dynamoDBConfiguration)
// Create DynamoDB document client
var dynClient = new AWS.DynamoDB.DocumentClient()
