crossdomain | JavaScript crossdomain access

I am trying to implement datatables draw() method in my Django application using AJAX. I have implemented both datatables and AJAX, which are working fine. However, I am facing a lot of challenges anytime I create a new object and call the draw() method so that datatables can refresh the table and show the newly created data the proper way. If I add the draw() method, the table does not get populated at all except I refresh the page.

main.js

My axios config

Using postman I get the cookie just fine, so it's an axios problem.

I'm trying to upload files to my S3 bucket via PresignedUrl Lambda function. everything works fine via post man. but the Browser based application is failing saying "SignatureDoesNotMatch"

My Lambda function region is ap-southeast-1.

but similar function works fine in ap-south1 (which is same timezone as mine). any idea why is this happening. could this be anything to do with the timezone difference between the server and client.

Please see my code below:

It is my first time using Azure Functions. I am trying to access a 3rd party API with an auth token passed in the header. I have had some success getting data back when I run the Azure function alone locally in that it logs the correct data to my console. I have deployed this basic function to Azure, and added * to the CORS list for testing. However, when I created a simple HTML file to host on our website with ajax within a script tag to get this data - so that I may eventually display it on the html page - nothing is returned. I have not found any other examples using my specific code base or with code this simple. There are no error messages, it just logs ''. Here is my html/JS script:

I need to have authentication using Google oauth2 with Passport Js in order to get user's email, despite setting CORS in backend and setting 'allow origin' in Axios I still get this error :

Trying to make an API get request from front-end (React) to back-end (Express/MongoDB) using Axios. If I use Postman to make the request it works fine (you can enter a user ID in the request body and get back an array of objects containing that user ID, which is what I want), but doing it from a front-end built in React doesn't work, I just get an empty array returned. As far as I can tell my API call from the front-end is exactly the same as the one I'm making in Postman! Can anyone shed any light on this?

This is the code making the get request from the front end:

I'm very new to JS/jQuery and have been struggling to add some search functionality to a site I'm building.

Basically, I've built a simple search field (#artist_search) that I'm trying to use to search through a JSON that is connected via a GET:

I have created my own restful application in PHP that exposes APIs to javascript application. Everything works smoothly except when I insert http_response_code in the response header.

Below is the function I use to print the data in json format. I set the http_response_code() based on the error code I need to use (200, 404, 400, 401 etc).
