Twilio Autopilot Dynamic Say Action with variables from memory - twilio

Question

I have a situation where I'm able to store additional details about a customer in memory . But Im unable to access them in the Task Definition .
E.g I'm storing the customer's last purchase amount and last purchase date to be presented if the customer wants to hear it as follows
{
"actions": [
{
"remember": {
"last_Purchase": "17585",
"last_Date":"25-Dec-2020"
}
},
{
"listen":True
}
]
}
They get stored in the memory . However I'm unable to use this in a subsequent task (I'm not using it in the same task as Twilio doesnt supports it ) .
In a subsequent task I want to be able to create a dynamic Say in a task as follows
Dear Customer your last purchase is {memory.last_Purchase} on {memory.last_Date}.
But I guess the syntax is wrong or the way I'm accessing the memory variable is wrong .
Request guidance .

In JavaScript, you'll need to put a money sign ("$") in front of the brackets surrounding your variable name, so your Say Action would look something like this in JavaScript, like in a Twilio Function:
say = {
"say": `Dear Customer your last purchase is ${memory.last_Purchase} on ${memory.last_Date}.`
}
Additionally, objects saved with the Remember Action are placed at the top-level of the Memory object, so make sure you pull it out with JSON.parse:
let memory = JSON.parse(event.Memory);
The total JS code (say, in a Twilio Function) would look something like
exports.handler = function(context, event, callback) {
let actions = [];
let say = {};
let memory = JSON.parse(event.Memory);
say = {
"say": `Dear Customer your last purchase is ${memory.last_Purchase} on ${memory.last_Date}.`
}
actions.push(say);
let respObj = {
"actions": actions
};
callback(null, respObj);
};
Of course, alternatively, you could use
say = {
"say": "Dear Customer your last purchase is " + memory.last_Purchase + "on
" + memory.last_Date
}
