I have create a custom HTML page for Find Existing Location analysis following this link  https://developers.arcgis.com/javascript/3/jsapi/findexistinglocations-amd.html#event-job-submit

I am able to do perform attribute and spatial query at the published feature layer.When I am loading secure feature layer(shared with organization) on the map using token. So layer is loading on the map and the "Add Expression"is also adding to layer in findexistinglocations widget. But whenever load the layer , this error is coming.
