This has been giving me fits. Why doesn't this work?

function showCoordinatesNew(evt) {
 var mp = esri.geometry.webMercatorToGeographic(evt.mapPoint);
 console.log(mp.x+","+mp.y); //<-- returns correct geographic coordinates
 console.log(mp.spatialReference.wkid); //<-- returns wkid 4326
 var params = new esri.tasks.ProjectParameters();
 params.geometries = mp;
 //setting output Spatial Reference to Nevada State Plane West Zone NAD83
 params.outSR = new esri.SpatialReference({wkid: 102709});
 //execute project function, callback will be picked up by onProjectComplete
 gsvc.project(params); //<-- fails with Uncaught TypeError: Cannot read property 'spatialReference' of undefined
function onProjectComplete(geometries) {
 //project function never gets this far.
 var mp = geometries[0];
 console.log("Returned Coordinates: " + mp.x + "," + mp.y);

function onError(message) {

Here is the full error:

Uncaught TypeError: Cannot read property 'spatialReference' of undefined
