How to access lex session attributes in AWS lambda function - session

Question

I wrote the below code to assign session attributes from my application,
var lexruntime = new AWS.LexRuntime();
var params = {
botAlias: 'PizzaOrder', /* required */
botName: 'PizzaOrder', /* required */
inputText: 'profile list', /* required */
userId: '160728846416', /* required */
sessionAttributes: {
//'<token>': cookies['token'],
'token': cookies['token'],
'communityid':cookies['communityid'],
'selectedAuthorId':cookies['selectedAuthorId'],
'kfurl':cookies['kfurl']
/* '<String>': ... */
}
};
//console.log("Cookies in index js "+cookies['token']);
lexruntime.postText(params, function(err, data) {
if (err) console.log(err, err.stack); // an error occurred
else console.log(data); // successful response
});
I want to access the session attributes in my lambda function using intentRequest.sessionAttributes.seesionattributename in the below code and as shown below
function GetAuthors2(intentRequest,callback) {
const token2 = String(intentRequest.sessionAttributes.token);
const communityid2 = String(intentRequest.sessionAttributes.communityid);
// --------- http start ---------
var options = {
hostname: 'kf6-stage.rit.albany.edu',
port: 443,
path: '/api/communities/'+communityid2+'/authors',
headers: {
'Content-Type' : "application/json",
'Authorization' : "bearer " + token2
}
};
https.get(options, (resp) => {
console.log("#in Http");
let data2 = '';
// A chunk of data has been recieved.
resp.on('data', (chunk) => {
data2 += chunk;
});
// The whole response has been received. Print out the result.
resp.on('end', () => {
var data_2 = JSON.parse(data2);
const cList2 = [];
data_2.forEach(function(i){
cList2.push(i.firstName);
});
callback(close(intentRequest.sessionAttributes, 'Fulfilled',
{
contentType: "PlainText or SSML",
content: "Hi,You have "+cList2.length+" authors registered Bharghav. Here is the list \n"+ cList2.join()
}
));
});
});
}
but after the intent request I am getting the following response "Sorry, I was unable to process your message. Try again later."
If I hardcode the values in the lambda function it works fine.
Can someone kindly tell me where am I doing wrong in accessing the session attributes??

Answer 1

This worked for me. accessing the session attributes from the event/input. Then accessing the attribute by name.
exports.handler = async (event) => {
var attributes = event['sessionAttributes'];
console.log('attrs; ',attributes);
let sessValue;
if( attributes != null)
sessValue = attributes['fileName'];
