I am having trouble displaying features from certain layers in 'Export Web Map'.
The tool would run successfully and the basemap would render correctly, but features from a map service layer would not render at all.
These features show just fine on a web map.
This is happening in both ArcMap and ArcGIS Server print service.
If I check the log entries on AGS I would see a bunch of errors like this:
[layer name]: Image compressor error. Cannot compress/decompress the image.
