TypeError: clazz is not a constructor, not sure what the issue is?

hi Im trying to adjust the example ShowVertex feature action to suite my porposes by adding another feature action to the demo widget and send the name and ID of a feature to the widget.

I have , heres my feature action code

define([
   'dojo/_base/declare',
   'jimu/BaseFeatureAction',
   'jimu/WidgetManager'],
   function(declare, BaseFeatureAction, WidgetManager){
      var clazz = declare(BaseFeatureAction, {

iconFormat: 'png',

      isFeatureSupported: function(featureSet){
         return featureSet.features.length > 0 && featureSet.features[0].geometry.type !== 'point';
      },

      onExecute: function(featureSet){
         WidgetManager.getInstance().triggerWidgetOpen(this.widgetId)
         .then(function(myWidget) {
            var id
            var name
         featureSet.features.forEach(function(f){
            id = f.id
            name = f.name
         });
      myWidget.AddtoSelected(name,id);
   });
   }
});
return clazz;
});

Im getting a create widget error

when debuggin in chrome I get

As this error report doesnt mention any of my widget files Im rather confused on where to find the problem, Im assuming its in the feature action as thats where clazz is.

Could someone help point me in the right direction to resolve this error?

Thanks

James,

Normally this means you have introduced a syntax error in your code, not closed a bracket, forgot a comma, etc. What does your mainifest.json look like? What does your Widget.js look like?
