Spine 3.8.94 is failing to load during a command-line export.
The error is pretty limited in what it says went wrong:
JSON export: party p01
ERROR: Unable to start: Spine 3.8.94

I've saved my spine files as the latest version so that they'll work with 3.8.94, so going back to an earlier version is probably not an option.
Exporting from the Spine editor via the GUI seemed to work though so I've done that for now.
Is there anywhere I can look for more logging?
