What could be the reason for the absence of the HTTP response in the network tab of the Chrome debugger?

After utilizing Postman to test my web service, I was able to find the WS's response in the http response body.

However, when I made a call using ajax in my web application, I encountered an issue where I could no longer locate the response. The tab simply displayed a message indicating "This request has no response data available."

Below is the ajax call that I made:

$.ajax({
        url: url,
        method: "POST",
        data: params,
        success:function(response) {
            console.log(response); // unfortunately, no console output here!
            console.log('response');
        },
        error:function(){
            console.log("error");
        }

    });

Hello there, Here's a suggestion for you.

When working with ajax, make sure your params include an action like 'get_pincodes'. Upon handling this, remember to set action as 'get_pincodes' and use echo json_encode($response);exit;

Example:

if($_REQUEST['action'] != "" && $_REQUEST['action'] == 'get_pincodes'){
    $response = array();
    $response[] = "500113";
    $response[] = "500114"; // etc....

    echo json_encode($response);exit;   
}

One potential solution could be to include charset=utf-8 in the Content-Type of the response headers like this: Content-Type: application/json; charset=utf-8

$.ajax({
    url: url,
    method: "POST",
    dataType: "json",
    headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json;charset=utf-8'
    },
    data: params,
    success:function(response) {
        console.log(response); // avoid using console here!
        console.log('response');
    },
    error:function(){
        console.log("error");
    }

});
