Internally, this is the only reference I could find for "ObjectExporterService" from 2010:
"The issue was not the permissions on the folder, although this is required once you make the following changes:
Apparently the Import/Export BLCLI commands cannot get executed using NSH or scripting in general when executed on an AppServer that is configured as a job server only instance. From the information I got from support, this operation requires the AppServer to be configured as a configuration instance."
Does this apply to your situation?
Yes, that could well be the answer as the server is a job server only.
Thanks very much. I'll see if I can change the configuration appropriately
Confirmed. Works on a standard AppServer.
Thanks for verifying. What version of BSA are you running?
