Recall dynamodb table with Alexa - amazon-web-services

Question

Im trying to create a skill that will scan or query my dynamodb table which includes a date column, filmanme, and time.
Here is the code i have so far.
console.log('Loading function');
var AWSregion = 'us-east-1'; // us-east-1
var AWS = require('aws-sdk');
var dclient = new AWS.DynamoDB.DocumentClient();
var getItems = (event, context, callback)=>{
dclient.get(event.params,(error,data)=>{
if(error){
callback(null,"error occurerd");
}
else{
callback(null,data);
}
});
};
exports.handler = getItems;
exports.handler = (event, context, callback) => {
try {
var request = event.request;
if (request.type === "LaunchRequest") {
context.succeed(buildResponse({
speechText: "Welcome to H.S.S.M.I skill, what would you like to find",
repromptText: "I repeat, Welcome to my skill, what would you like to find",
endSession: false
}));
}
else if (request.type === "IntentRequest") {
let options = {};
if (request.intent.name === "cinema") {
if (request.intent.slots.cimema !== undefined)
var sign = request.intent.slots.cinema.value;
//Check sign is valid
if (sign === undefined || sign === null) {
options.speechText = " sorry, i didn't understant your question. can you say that again?";
options.endSession = false;
context.succeed(buildResponse(options));
return;
}
if (request.intent.slots.zodiac !== undefined && !ValidateZodiacSign(sign)) {
options.speechText = ` The Zoadiac sign ${sign} is not a valid one. Please tell a valid zodiac sign .`;
options.endSession = false;
context.succeed(buildResponse(options));
return;
}
cinema(sign, function (cinema, error) {
if (error) {
context.fail(error);
options.speechText = "There has been a problem with the request.";
options.endSession = true;
context.succeed(buildResponse(options));
} else {
options.speechText = todaysFortune;
options.speechText += " . Have a nice day ahead . ";
options.sign = sign;
options.cardText = todaysFortune;
options.endSession = true;
context.succeed(buildResponse(options));
}
});
} else if (request.intent.name === "AMAZON.StopIntent" || request.intent.name === "AMAZON.CancelIntent") {
options.speechText = "ok, good bye.";
options.endSession = true;
context.succeed(buildResponse(options));
}
else if (request.intent.name === "AMAZON.HelpIntent") {
options.speechText = "My skill will read your table depending on what is asked. For example, you can ask what about a specific date. Please refer to skill description for all possible utterences.";
options.repromptText = "What is the data sign you want to know about today? If you want to exit from my skill please say stop or cancel."
options.endSession = false;
context.succeed(buildResponse(options));
}
else {
context.fail("Unknown Intent")
}
}
else if (request.type === "SessionEndedRequest") {
options.endSession = true;
context.succeed();
}
else {
context.fail("Unknown Intent type");
}
} catch (e) {
}
};
function buildResponse(options) {
var response = {
version: "1.0",
response: {
outputSpeech: {
"type": "SSML",
"ssml": `<speak><prosody rate="slow">${options.speechText}</prosody></speak>`
},
shouldEndSession: options.endSession
}
};
if (options.repromptText) {
response.response.reprompt = {
outputSpeech: {
"type": "SSML",
"ssml": `<speak><prosody rate="slow">${options.repromptText}</prosody></speak>`
}
};
}
return response;
}
function readDynamoItem(params, callback) {
var AWS = require('aws-sdk');
AWS.config.update({region: AWSregion});
var dynamodb = new AWS.DynamoDB();
console.log('reading item from DynamoDB table');
dynamodb.scan(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else{
console.log(data); // successful response
callback(JSON.stringify(data));
}
});
var docClient = new AWS.DynamoDB.DocumentClient();
//Get item by key
docClient.get(params, (err, data) => {
if (err) {
console.error("Unable to read item. Error JSON:", JSON.stringify(err, null, 2));
} else {
console.log("GetItem succeeded:", JSON.stringify(data, null, 2));
callback(data.Item.message); // this particular row has an attribute called message
}
});
}

and here is my DBHandlder
const AWS = require('aws-sdk');
AWS.config.update({
region: "'us-east-1'"
});
var docClient = new AWS.DynamoDB.DocumentClient();
var table = "Cinema";
var getItems = (Id,callback) => {
var params = {
TableName: "cinema",
Key: {
"Id": Id
}
};
docClient.get(params, function (err, data) {
callback(err, data);
});
};
module.exports = {
getItems
};
i'm very new to this and i cant find muchsupport online for the skill i want to produce or anything similar.
I created a lambda function which works and will find the corresponding movie when i configure the test function to find a specified date, however this does not work with alexa
any input is helpful.
