A Custom Script agent has quit gathering data with FMS errors "Failed to create a topology object" (4324738)

A custom agent that ran for several weeks has quit gather data. It shows as active.

I have tried restarting everything I could and the custom agent script output looks good when executed from the cmd prompt.

Errors seen in FMS log:

2014-11-14 15:18:19.055 ERROR [Data-3-thread-21108] com.quest.nitro.service.topology.TopologyService - Failed to create a topology object with name Sbc2CatTlk_Agent_Table_Sbc2CatTlk: {unit=all-hk, agent=aea2cd9f-1b62-455e-98df-ebbce6291b57, name=Sbc2CatTlk}: com.quest.nitro.service.sl.interfaces.topology.IncompleteIdentityException: Sbc2CatTlk_Agent_Table_Sbc2CatTlk.it

Whenever a script is modified, one must always reload it in the Administration | Tooling | Script Agent Builder to increase the version and redploy the package to the FglAM client.

1) Load the script via Administration | Tooling | Script Agent Builder increasing the version from 1.0.0 to 1.0.1.

2) Push out the cartridge package update to the FglAM.
