mapView goTo not working

I wrote some code to swap out the basemap layer from a default, USGS layer to a less stable Wisconsin based one. The problem is that the mapview's goTo doesn't work and the map remains zoomed way out. If I used a Wisconsin focused base map as the default then it works, but anything with a national extent fails

This is the code fragment

if (this.basemaps[1].basemapObject.baseLayers.toArray()[0].loadError == null) {

        this.mapView.map.basemap = this.basemaps[1].basemapObject;

        // remove ESRI default layer        

        console.log("mapView is ",this.mapView);

        this.basemaps.splice(0,1);

        this.removeBasemap("USGS");

        this.mapView.goTo({

          center: this.mapView.center,

          zoom: 3

        });

      }

      clearInterval(interval);

    }, 10000);

 

If I check the mapView's zoom property it would be at -1. 

What else do I need to do to get this to work? 

Alternatively does ESRI have basemap layers for individual states?

What version of the API are you using?  I saw a similar problem in 4.23, and it's discussed here.
