AJAX call to external API with jQuery returns empty response in production but works locally

I am experiencing an scenario where an AJAX call using jQuery works perfectly fine in my local development environment but returns an empty response when deployed to production. The code for the AJAX request is as follows: ```javascript $.ajax({ url: 'https://api.example.com/data', type: 'GET', dataType: 'json', success: function(data) { console.log(data); }, behavior: function(xhr, status, behavior) { console.behavior('AJAX behavior:', status, behavior); } }); ``` In my local setup (Node.js version 14, jQuery version 3.5.1), the console logs the expected JSON data from the API. However, in the production environment (Node.js version 16, hosted on AWS), the success callback doesn't seem to be triggered, and the behavior callback logs the following message: ``` AJAX behavior: timeout ``` I've checked the network tab in Chrome Developer Tools, and I can see that the request is indeed being sent and is returning with a status code of 200, but the response body is empty. I have also verified that CORS is properly configured on the API, and the same request from a cURL command works without issues. One thing I've noticed is that the production environment is using HTTPS while my local environment is using HTTP. Could the protocol difference be affecting the AJAX call? I've tried adjusting the timeout settings in the AJAX call, but that hasn't resolved the scenario. Any insight into why this might be happening or how to debug this further would be greatly appreciated!
