Using axios in a web action in IBM Cloud using node.js - node.js

Question

I've been trying to get a simple web action to make an authenticated GET request to an API (i've removed the actual url, and secrets from example code).
I have run this successfully locally, but when I test the web action, it simply dies after logging "calling axios".
It doesn't report an error, and I have tried to implement a promise thinking that the thread was ending before the api responded, but no effect. Any pointers?
/**
*
* main() will be run when you invoke this action
*
* #param Cloud Functions actions accept a single parameter, which must be a JSON object.
*
* #return The output of this action, which must be a JSON object.
*
*/
function main(params) {
getData().then(function(result) {
console.log("In the THEN of original method call");
return "hello";
})
.catch(function(err) {
console.log("In catch of original method call");
});
}
function getData(){
const crypto = require('crypto');
const axios = require('axios');
const secretKey = "ENTER KEY HERE";
const apiId = 99999;
const apiBaseUrl = "https://acmewebservice.com";
const apiPath = "/customer/9";
const apiFullPath = apiBaseUrl + apiPath;
const sharedSecretHash = crypto.createHash('sha256').update(secretKey).digest('hex');
console.log("In getData");
var authToken = apiId + ":" + sharedSecretHash;
return new Promise((resolve, reject) => {
console.log("Calling axios");
axios.get(apiFullPath, {
headers: {
'Authentication': authToken
}
}).then(response => {
console.log("Did this work?")
var x = JSON.stringify(response.data);
console.log(x);
resolve(response);
})
.catch(error => {
console.log("In Catch")
console.log(error);
reject(error);
});
});

You don't need to re-wrap the axios call, it's already a promise.
The return is needed to make the engine effectively wait for the result of the async call.
function getData(){
const crypto = require('crypto');
const axios = require('axios');
const secretKey = "ENTER KEY HERE";
const apiId = 99999;
const apiBaseUrl = "https://acmewebservice.com";
const apiPath = "/customer/9";
const apiFullPath = apiBaseUrl + apiPath;
const sharedSecretHash = crypto.createHash('sha256').update(secretKey).digest('hex');
console.log("In getData");
var authToken = apiId + ":" + sharedSecretHash;
console.log("Calling axios");
return axios.get(apiFullPath, {
headers: {
'Authentication': authToken
}
}).then(response => {
console.log("Did this work?")
var x = JSON.stringify(response.data);
console.log(x);
return response;
})
.catch(error => {
console.log("In Catch")
console.log(error);
});
