Hello all,  
I am currently having troubles using the HubSpot CMS serverless function to connect to an AWS API.  
The API end point functions correctly and has been tested using Postman.  
I would like to use a serverless function in a NodeJS environment to connect to the API and send the result to the HubSpot CMS.  
I have set up a the NodeJS serverless function following this tutorial: [Get started with serverless functions - HubSpot docs](https://developers.hubspot.com/docs/cms/guides/getting-started-with-serverless-functions)  
I have now replaced the body of the tutorial function with a simple Http request using the built in https module included in NodeJS but it does not seem to be connecting to my API.  
For the purpose of this question I have included the code snippet with an example http request that follows the same strategy I have been trying to implement with my own API.

Running the serverless function below I do not seem to be hitting the API code and the functionResponse is not updated with the result of the call.

```lia-code-sample
exports.main = (context, sendResponse) => {
 // your code called when the function is executed
 var functionResponse = "Congrats! You've just deployed a Serverless Function."

 const https = require('https');
 let data = '';
 https.get('https://api.nasa.gov/planetary/apod?api_key=DEMO_KEY', (resp) => {

 // A chunk of data has been received.
 resp.on('data', (chunk) => {
 data += chunk;
 });

 // The whole response has been received. Print out the result.
 resp.on('end', () => {
 console.log(JSON.parse(data).explanation);
 functionResponse = JSON.parse(data).explanation;
 });

 }).on("error", (err) => {
 console.log("Error: " + err.message);
 });

 sendResponse({body: functionResponse, statusCode: 200});
};

```

Thank you for your help!

Hello @EPasiak

Welcome to the Community!

I am wondering if @lynton can posit some thoughts here. I _believe_ he is deep into serveless now. Could be wrong

I was able to resolve the issue!

The logs were not updating properly and I was not seeing the most recent log when using the hs logs --follow CLI command.  
When I checked the logs using hs logs --latest I was getting the expected result.

Thank you for your response!
