I have been trying to use paper-autocomplete to get auto suggestions for an input field. I'm using Polymer 3.0

I'm getting auto suggestion drop down when I type something in the input field, but it is showing as empty.

```
import { PolymerElement, html } from "./node_modules/@polymer/polymer/polymer-element.js";
import './node_modules/@fluidnext-polymer/paper-autocomplete/paper-autocomplete.js';

class MyBot extends PolymerElement {
   static get template()
   {
       return html`
           <paper-autocomplete label="Search Something" source={{array}}> 
           </paper-autocomplete>

           <iron-ajax
        auto
        id= "getSuggestions"
                url=""
                handle-as="json"
                on-response="autosuggest"
                debounce-duration="300">
       </iron-ajax>
    `;
   }

   static get properties()
   {

   };

   autosuggest(responses)
   {
       console.log('questions');
       let rows = responses.detail.response; //console.log(rows);
       let result=[]; 
       for(var i in rows)
       result.push( rows [i]['question']);
       this.array=result;
    }

}

```

I'm getting these errors 

1. Could not find style data in module named paper-material-styles style-gather.js:82

2.the autosuggestion drop down is not showing any data. (Sorry I could't post photo because of less reputation)

Got the suggestions by using 

```
<paper-autocomplete label="Search Something" source={{array}}  text-property="key"> </paper-autocomplete>

```

where key is the key in the array
