title: Autodesk Forge GetBulkProperties2
body: <p>I'm currently trying to <code>viewer.model.getBulkProperties2()</code> because I need the externalIds of the model. I've been using a loop with <code>getProperties()</code> to get the externalId but whenever I try it with very large NWDs firefox / chrome crashes.</p>
  <p>The thing is, even if I specify in the options object that I need the external ids with <code>needsExternalId:true</code>, the function is not returning them. This is the affected portion of my code :</p>
  <pre><code>viewer.model.getBulkProperties2(dbids,{propFilter:params,needsExternalId:true,ignoreHidden:false,categoryFilter:null},(res)=&gt;{
      console.log(res)
  });
  </code></pre>
  <p>The property I'm using is just Name, and this is the returned <code>res</code> variable:</p>
  <pre><code>[
      {
          &quot;dbId&quot;: 2,
          &quot;properties&quot;: [
              {
                  &quot;displayName&quot;: &quot;Nombre&quot;,
                  &quot;displayValue&quot;: &quot;Nivel 1&quot;,
                  &quot;displayCategory&quot;: &quot;Datos de identidad&quot;,
                  &quot;attributeName&quot;: &quot;Name&quot;,
                  &quot;type&quot;: 20,
                  &quot;units&quot;: &quot;&quot;,
                  &quot;hidden&quot;: false,
                  &quot;precision&quot;: 0
              }
          ]
      },
      {
          &quot;dbId&quot;: 3,
          &quot;properties&quot;: [
              {
                  &quot;displayName&quot;: &quot;Nombre&quot;,
                  &quot;displayValue&quot;: &quot;Nivel 2&quot;,
                  &quot;displayCategory&quot;: &quot;Datos de identidad&quot;,
                  &quot;attributeName&quot;: &quot;Name&quot;,
                  &quot;type&quot;: 20,
                  &quot;units&quot;: &quot;&quot;,
                  &quot;hidden&quot;: false,
                  &quot;precision&quot;: 0
              }
          ]
      }
  ]

  <p>Am I messing anything up?</p>
