Object data null sms still sent twilio authy - firebase

Question

Im trying to implement the authy-node phone verification with firebase functions and my app in react-native the message is sent to the correct mobile phone but for some reason the data I get back from the api is null any ideas out there
My Api firebase functions
import * as functions from 'firebase-functions';
const authy = require('authy')('mySecret');
export const getCode = functions.https.onCall((data, context) => {
const {
number, countryCode
} = data;
return authy.phones().verification_start(number, countryCode, { via:
'sms', locale: 'en', code_length: '4' }, (err: any, res: any) => {
if (err) {
throw new functions.https.HttpsError(err);
}
return res;
});
});
and this is my call from my app
export default class test extends Component {
constructor() {
super();
}
componentWillMount() {
const getCode = firebase.functions().httpsCallable('getCode');
getCode({number: 'theCorrectNumber', countryCode: '44'})
.then(function (result) {
const data = result;
console.log(data)
}).catch( function (error){
console.log(error)
})
}
render() {
return (
<View/>
);
}
}

From what I can see in the Authy Node library that I'm assuming you're using, making a request to the API does not return a Promise. Instead it is built with request and responds to asynchronous requests using callbacks only. You do deal with the callback, but you are returning the result of calling the asynchronous function, which is null, rather than the result from the callback.
Perhaps including a callback as part of the function call would work better:
import * as functions from 'firebase-functions';
const authy = require('authy')('mySecret');
export const getCode = functions.https.onCall((data, callback) => {
const { number, countryCode } = data;
return authy
.phones()
.verification_start(
number,
countryCode,
{ via: 'sms', locale: 'en', code_length: '4' },
callback
);
});
You can then use it like this:
export default class test extends Component {
constructor() {
super();
}
componentWillMount() {
const getCode = firebase.functions().httpsCallable('getCode');
getCode({ number: 'theCorrectNumber', countryCode: '44' }, (err, res) => {
if (err) {
throw new functions.https.HttpsError(err);
}
const data = res;
console.log(data);
});
}
render() {
return <View />;
}
}
Let me know if that helps at all.
