Custom widget extension issue in thingworx composer

[Rajkumar_20673]

Built an Custom widget, based on the Polymer JavaScript  , when Extension ran through the Web Application, the chart looks like below Image: 
 

 
 
After importing the Custom-widget.zip file in to the Thingworx and when tried to show it on a Mashup, no chart appears 
 

And when viewed, following error is seen in the web console: 

Thanks

Hi @Rajkumar_20673

You provided the image that you see from the "Web Application."  Are you referring to a view of the mashup or some other tool?  Even though you're not seeing it in the mashup builder, what do you see when you click "View Mashup?"  At what point does the error occur?  In the Mashup builder or when you're viewing the mashup?

Regards.

Hi @slangley 

Programming Language used Polymer Js

After built, Mashup widget I.e (extension.zip) file. After importing file into mashup. It the showing none 

After saving the mashup and when we click on view mashup. 

Where we are seeing the mashup output in browser. It is showing blank.

Hi @Rajkumar_20673.

In regard to the mashup, when you developed the extension, did you include a preview for your widget that would appear in the mashup builder?  In regard to the 404 error, have you checked for typos or missing extensions? 

Regards.
