I keep getting this error while trying to get map data. I am not sure what I am doing incorrectly. I do this because there is a known bug in 2016.1 where you can't map to layer attributes without a raster image of some type in the scene or a layer that has an attribute whose named is shared with the rule*(See Cheryl's comment below).
I can get it to work at a very low resolution when zoomed out, but the same is not possible when zoomed in. Is there any guidance between the relationship between the resolution or extent for this feature?
