This fragment from src/Main/fg_commands.cxx is the source of that error
message. If you look closely, you'll see a file name is supposed to be in
those quote marks. A file name that appears not to exist in the current case.
It to me, for that to happen globals->resolve_maybe_aircraft_path(file.str())
is returning a null. Is FG_AIRCRAFT set to a valid path or unset?
Also, this is apparently nasal related. Is the path allowed in Nasal/IOrules?

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
