title: Angular 8 + Kendo Common: Error in Illegal state: Could not load the summary for directive DraggableDirective
body: <p>I am running latest Angular 8 with the following Kendo / Telrik packages:</p>
  <pre><code>&quot;@telerik/kendo-draggable&quot;: &quot;^2.2.0&quot;,
  &quot;@progress/kendo-angular-buttons&quot;: &quot;^5.4.3&quot;,
  &quot;@progress/kendo-angular-common&quot;: &quot;1.2.2&quot;,
  &quot;@progress/kendo-angular-dateinputs&quot;: &quot;^4.3.1&quot;,
  &quot;@progress/kendo-angular-dropdowns&quot;: &quot;4.3.0&quot;,
  &quot;@progress/kendo-angular-excel-export&quot;: &quot;^3.1.4&quot;,
  &quot;@progress/kendo-angular-grid&quot;: &quot;4.7.3&quot;,
  &quot;@progress/kendo-angular-inputs&quot;: &quot;6.6.1&quot;,
  &quot;@progress/kendo-angular-intl&quot;: &quot;^2.0.2&quot;,

  &quot;@progress/kendo-theme-default&quot;: &quot;latest&quot;,
  &quot;@progress/kendo-ui&quot;: &quot;2020.2.617&quot;,
  </code></pre>
  <p><strong>This is my error message:</strong></p>
  <p><em>ERROR in Illegal state: Could not load the summary for directive DraggableDirective in node_modules/@progress/kendo-angular-common/dist/es2015/index.d.ts.</em></p>
  <p>The error message does not occur when I do an <code>ng start</code> but if I build with the below line, the error occurs:</p>
  <pre><code>node --max-old-space-size=8192 ./node_modules/@angular/cli/bin/ng build --prod --aot --vendor-chunk=true --commonChunk=true --deleteOutputPath=true my-app
  </code></pre>
  <p>Also without the node memory boost, the error still happens:</p>
  <pre><code>ng build --prod --aot --vendor-chunk=true --commonChunk=true --deleteOutputPath=true my-app
  </code></pre>
