I'm a total noob when it comes to the JavaScript API. I'm teaching myself. I'm trying to use the UniqueValueRenderer to render one of my feature layers. When I do it with a simple renderer in the code that's commented out it works. When I use UniqueValueRenderer or ClassBreaksRenderer the layer doesn't draw. What am I missing?
Thanks
require(["esri/map",
"esri/layers/FeatureLayer",

function(Map,
FeatureLayer,
SimpleLineSymbol,
UniqueValueRenderer,
InfoTemplate,

Color) {
var map = new Map("map", {
basemap: "streets",

});
// create the FeatureLayer object
var sewerLines = new FeatureLayer("http://maps.lrwu.com/wa/rest/services/MoreLayers/MapServer/1", {
mode: FeatureLayer.MODE_ONDEMAND,
outFields: ["UPS_MH", "DWN_MH", "PIPLEN", "PIPDIA", "UPS_DWN", "UNITTYPE"],

displayOnPan: false
});
//Set the symbol and render the sewerLines
//var symbol = new SimpleLineSymbol(
// SimpleLineSymbol.STYLE_SOLID,
// new Color([255,0,0,1]),
// 3);
var renderer = new UniqueValueRenderer(null, "UNITTYPE");
renderer.addValue("GRAVITY", new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([0, 0, 0, 1]), 3));
renderer.addValue("FORCE", new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([ 0, 0, 255, 1]), 3));
renderer.addValue("PRVGRV", new SimpleLineSymbol(SimpleLineSymbol.STYLE_SOLID, new Color([0, 128, 0, 1]), 3));
sewerLines.setRenderer(renderer);
// addLayers must use an array to list layers added.
map.addLayers([sewerLines, manholes, eadFacilities]);
});
