When you download the app, ExB server will compile the widgets. Can you run "npm run build:prod" in the client folder to see if there are any errors?</P> Fri, 06 Sep 2024 00:58:43 GMT Junshan_Liu 2024-09-06T00:58:43Z https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1522506#M14319 <P>On version 1.15, I am trying to download an application. When doing so, I get an error that states "Failed to load" and the file does not download. Has anyone else had this happen?</P><P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="Brian_McLeer_0-1723750844349.png" style="width: 400px;"><img src="https://community.esri.com/t5/image/serverpage/image-id/112521iA41B8A128CA593AE/image-size/medium?v=v2&amp;px=400" role="button" title="Brian_McLeer_0-1723750844349.png" alt="Brian_McLeer_0-1723750844349.png" /></span></P><P>&nbsp;</P> Thu, 15 Aug 2024 19:40:58 GMT https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1522506#M14319 Brian_McLeer 2024-08-15T19:40:58Z https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1522747#M14326 <P>Do you see any console error on the server side when you see this error?</P> Fri, 16 Aug 2024 07:59:37 GMT https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1522747#M14326 Junshan_Liu 2024-08-16T07:59:37Z https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1535571#M14723 <P>I also experienced this when updating to Developer Edition 1.15 and was unable to download my app. I think it ended up being a custom widget in my extensions inside the client folder. After I deleted that, I was then able to successfully download my app, although the custom widget I deleted wasn't in the app I was trying to download.</P> Thu, 05 Sep 2024 16:50:41 GMT https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1535571#M14723 Trevor_Oatts 2024-09-05T16:50:41Z https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1535774#M14735 <P>I guess there may be errors when compiling your custom widget.

Before that, I did do a full removal and install of 1.15.</P> Tue, 10 Sep 2024 16:40:19 GMT https://community.esri.com/t5/arcgis-experience-builder-questions/failed-to-load-error-trying-to-download-ex-builder/m-p/1536945#M14768 Brian_McLeer 2024-09-10T16:40:19Z
