@skmedia So how can I get title field values from my database to backend to show the output in frontend repeater I’m not able to understand, actually I’m confused here about what statement should I use here so it will start taking values from my database.
By the way when I’m using the below code it not showing any error but it also not showing any result to the repeater.
Now my backend code looks like this:

let callId = wixData.get("myDatabaseName", 'title');

  
//imaginary url example below
 const response = await fetch("https://www.exampleapi.com/data/d5/feed?&id=" + id + "&key=" + apiKey, {
        method: 'get'
    });
