I received this error when I tried to use PSOS to install a server-side plugin but did not have the ability to install server-side plugins enabled in the FMS Admin Console.

I got this error trying to go to a field with "Go To Object". The problem was that the field was actually grouped, so therefore inaccessible. Ungroup and it works.
