I may be barking at the moon for help on this one, but once in a blue moon, the GenerateGeodatabaseAsync task succeeds but the CopyToAsync step fails. The client ends up with a zero size GDB and the app crashes with the following exception:
"Item not found in the database. (Table, domain, relationship class, etc.) : gpkg_contents."
I think it's a network glitch, but if anyone has any insight on this issue I'd really appreciate it.
