I’m having the same error with regular transcoded by shotgun versions.
The problem is Shotgun does not longer comes with the sg_department field by default in Versions, so you either delete it from shotgun_fields_config_standard.mu or add it as a field to your versions.
Providing that this field is no longer a default one for versions, shouldn’t the plugin for RV come with this field as “optional” and not required? Is actually a way to do this in the shotgun_fields_config_standard.mu ? For compatibility with projects who has them and the ones who don’t?
