How do I obtain available worker count in twilio function calling node library? - twilio

Question

Im looking to invoke a twilio function and obtain a count of available workers.
I have a feeling it might be related to TaskQueues and the Matching Workers who are available?
Ive come up with the following. However, users are still listed as available when they are interacting with a task, which means this wont work necessarily.
exports.handler = function (context, event, callback) {
const client = require('twilio')(context.ACCOUNT_SID, context.AUTH_TOKEN);
client.taskrouter
.workspaces('eee')
.workers.list()
.then(workers => {
data = {
availWorkersCount: Object.keys(workers.filter(x=> x.available === true && x.attributes.includes("sales"))).length
};
const response = new Twilio.Response();
response.appendHeader('Access-Control-Allow-Origin', '*');
response.appendHeader('Access-Control-Allow-Methods', 'OPTIONS POST GET');
response.appendHeader('Access-Control-Allow-Headers', 'Content-Type');
response.appendHeader('Content-Type', 'application/json');
response.setBody(data);
callback(null, response);
});
};

I know this is a bit late, but this is the chunk of code I use in a twilio function to do just this. We call the function from the studio flow and use the results to decide if I am going to route the call into voicemail or play some IVR options for picking what queue they should be put in. To use it you can pass in an optional skill to filter down the agents even more. We grab all available workers then filter down to only the ones that have the needed skill.
You could then take this and check if any of the agents that are available also have a task assigned to them then remove them from the count.
const fetch = require("node-fetch");
exports.handler = function(context, event, callback) {
let response = new Twilio.Response();
// Set the status code to 200 OK
response.setStatusCode(200);
// Set the Content-Type Header
response.appendHeader('Access-Control-Allow-Origin', '*');
response.appendHeader('Access-Control-Allow-Methods', 'OPTIONS, POST, GET');
response.appendHeader('Access-Control-Allow-Headers', 'Content-Type');
response.appendHeader('Content-Type', 'application/json');
let body = {
TotalAvailable: 0
};
let client = context.getTwilioClient();
client.taskrouter.workspaces(context.WorkspaceSid)
.workers
.list({
available: 'true',
limit: 50
})
.then((workers) => {
let agents = [];
let i = 0;
if(workers){
for(i = 0; i < workers.length; i++){
let worker = workers[i];
let item = {};
let attributes = JSON.parse(worker.attributes);
if(attributes && attributes.routing && attributes.routing.skills && attributes.routing.skills.length > 0){
item.skills = attributes.routing.skills;
item.nid = attributes.nid;
item.first_name = attributes.first_name;
item.last_name = attributes.last_name;
if(event.skill){
if(item.skills.includes(event.skill)){
// TODO: filter here
agents.push(item);
}
}else{
agents.push(item);
}
}
}
}
body.TotalAvailable = agents.length;
body.Agents = agents;
response.setBody(body);
callback(null, response);
})
.catch((ex) => {
body.error = true;
body.message = ex;
response.setBody(body);
callback(null, response);
});
};
