I am trying to write code that will query from a FeatureLayer using queryFeatures() and then call MapView goTo to zoom to that result. I am verifying that the query matches the attributes of the expected attributes when I query for a single objectid, but MapView goTo doesn't work when I try to zoom to the Graphics from the query.

However, if I create my own Graphics manually, it works as expected.

I have created an example with two buttons demonstrating my issue below. One button "workingButton" correctly zooms to some manually created Graphics. The other "notWorkingButton" tries to zoom to the result of a query, but doesn't work.

Vincent,

   Your query results need to be in the same spatial reference as the view. So you need to add outSpatialReference to queryParams

The spatial reference for the returned geometry. If not specified, the geometry is returned in the spatial reference of the queried layer.
      $('#notWorkingButton').click(function(){
        queryParams = app.pLineLayer.createQuery();
        queryParams.where = "OBJECTID = 1709";
        queryParams.outSpatialReference = view.spatialReference;
        app.pLineLayer.queryFeatures(queryParams).then(function(results){
          console.log("FeatureSet:", results);
          // go to that graphic
          view.when(function(){
            view.goTo({
              target: results.features[0], // Graphic object
              zoom: 20
            });
          });
        });
      });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Wouldn't it be nice if esri would mention in the API document that for graphic, geometry, etc. the spatial reference needs to be the same?
