[carb.flatcache.plugin] Type tag does not have a corresponding USD type

I got a warning when I am running my RL based robot: [Warning] [carb.flatcache.plugin] Type tag does not have a corresponding USD type. What does it means? Does it mean that I did something wrong in designing my robot?

Hi, I’m running into similar issues when I try to run replicator. How can I debug what these warnings and errors are referring to?
