I don't see where these "agnt" instances are, or what they are.
The schematic shown is not the "GNTAna.scs" (subcircuit?)
from which the errors are thrown.
If they're "A sources" and those "parameters" looking for
"component name" arguments are actually such (like cccs
wants a device, not nodes, for its control input), maybe it's
something like a netlisting:model statement argument order
mismatch?
However, I am getting entirely different and strange (the opamp seems not working at all) simulation waveform as compared to the waveform on page 12 of getting_started.pdf
