Sencha Architect model REST proxy gives error

Question

I have a local Nodejs server running on port 5000.

I use Sencha Architect and I want to load the API with the name "getUsers" from my Nodejs server.

Here's my model:

Ext.define('Hivemind.model.MyModel', {
     extend: 'Ext.data.Model',

     requires: [
         'Ext.data.field.Field',
         'Ext.data.proxy.Rest'
     ],

     fields: [
         {
             name: 'id'
         },
         {
             name: 'name'
         }
     ],

     proxy: {
         type: 'rest',
         url: 'http://localhost:5000/getUsers'
     }
 });

Note that "http://localhost:5000/getUsers" is also accessible simply by the browser

But it gives me the following error:

Please make sure that the URL you set for your proxy is either local, or similar to the URL you set in your projects settings. 

If you plan to use a different domain, please use a JsonP proxy.

If that matters, the project folder is saved somewhere on the Desktop, and the Nodejs Server files are stored on a different location
