Hi all,

I’m currently working on a coding where my customer able to track their parcels on my webpage instead of track directly on my forwarders’ page.

Please assist which part I’m doing wrong.

Input - #trackingInput
button - #button1
text - #result

This is how it looks

Front code

import {getResult} from 'backend/serviceModule';

$w.onReady(function ()  {

});

export function #button1_click(event, $w) {
 // This function was added from the Properties & Events panel. To learn more, visit http://wix.to/UcBnC-4
 // Add your code for this event here: 
  getResult($w("#trackingInput").value)
    .then(trackingInfo => $w("#result").text = trackingInfo + "°");
 
}

Backend Code

import {fetch} from 'wix-fetch';

export function getResult(tracking) {
 const url = 'http://17express .net/Tools/expresscheck.ashx?name=' + tracking
    console.log("url: " + url);

 return fetch(url, {method: 'get'})
        .then(response => response.json());
}

error message returned

invalid json response body at http://17express .net/Tools/expresscheck.ashx?name=KK202103011910290 reason: Unexpected token < in JSON at position 0
