I've testing adding secured services from ArcGIS Server to a Leaflet application. I'm using the guidance found on the ESRI Leaflet Examples. I am using data from my own server. I am getting the following error:
"Uncaught TypeError: Cannot read property of 'length' on undefined. Util.js:380."
Anyone have any ideas what's going on? I don't have any projects that require this, I'm just seeing if I can figure it out.
