This is a CORS (cross-origin resource sharing) issue and you do not have to delete/modify anything. You just have to enable the CORS request from your server-side and it will work fine.
const Map<String, String> corsHeaders = {
'Access-Control-Allow-Origin': '*',
'Access-Control-Allow-Methods': 'GET, POST, DELETE, PUT, PATCH, OPTIONS',
'Access-Control-Allow-Headers': '*',
}
Please add this headers on API end.

In my case, I have created a server with node.js and express.js, so I just added this middleware function that will run for every request.
```javascript
app.use(function(req, res, next) {
res.header("Access-Control-Allow-Origin", "*");
res.header("Access-Control-Allow-Methods", "GET,PUT,PATCH,POST,DELETE");
res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
next();
});
```
And BOOOOM! I received the data.
You just have to look at the settings to enable CORS for your server.
