How to define the attributes on my model and how to make a query on my route.js

On my route.js I have a line of code that is return this.store.findAll(auditTrail) so on my template.hbs

     <tr class="animated fadeIn">
       <td>{{auditTrail.eventName}}</td>
     </tr>
    {{/each}}

However, it returns nothing. This is my api endpoint /audit-trails/41?include=audit-trailable. My question, is there something wrong on my route.js or the way I define my model? Btw, this is my model. Please see model below

  eventName:               DS.attr('string'),
  ipAddress:               DS.attr('string'),
  userAgent:               DS.attr('string'),
  createdAt:               DS.attr('date'),
  deliveredAt:             DS.attr('date')

Ideally it should return something right. Below is the response I get when I was using Postman (edited)

You need to serialize the response from api. eventName iit’s not the same event-name.
