Null geometry

One of the Spatial Analyst tools we often use in ArcGIS is the Extract Values to Points tool. This allows us to take a point file (well locations in our case) and attach a value (elevations) from a raster image (a DEM) to each point. Today I was running it for the first time against an Image Service we recently published and I received a warning message,‘WARNING 000957: Skipping feature(s) because of NULL or EMPTY geometry’.
