In ArcGIS Pro, has anybody been able to generate a tile cache using the "Manage Tile Cache" geoprocessing tool, and an mxd as the input data source? When I try, it instantly fails with "ERROR 999999", sometimes it also tells me "The workspace is not connected." I set up as simple a project as possible, just to try getting this to work, but it won't. Anyone had success doing this? I'm using version 1.4.1.
