error writing Lambda function to insert record to DynamoDB table

I am new to AWS and Lambda. I created a test aws account and in DynamoDB created a table called guestbook with fields data and message. I tried the below code to insert record into table using lambda function.

and when I try to test this function, its giving this error

{ "errorMessage": "Syntax error in module 'lambda_function'" }

Can someone help me understand what is going wrong here.

FYI, I copied the code from example on Youtube .

Here is the code.

console.log('Starting Function');

const AWS = require ('aws-sdk');
const docClient = new AWS.DynamoDB.DocumentClient({ region: 'us-west-1' });
exports.handle = function (e, ctx, callback) {

    var params = {
        item: {
            date: Date.now(),
            message: "this is test"
        },
        TableName: 'guestbook'
    };

    docClient.put(params, function (err, data) {
       if (err) {
           callback(err, null);
       } else {
           callback(null, data);
       }
    });
}

The params was incorrect. The api's guide is here. The correct params should be like this.

console.log('Starting Function');
const AWS = require ('aws-sdk');
const docClient = new AWS.DynamoDB.DocumentClient({region: 'us-west-1'});
exports.handle = function (e,ctx, callback){


var params = {
    TableName: 'guestbook'
    Item: {
        date: Date.now(),
        message: "this is test"
    }
 }

 docClient.put(params, function(err, data) {
    if (err) {
        callback(err, null);
     } else {
        callback(null,data);
     }
 });
