I can't quite understand the error of my mod

[Demonic Goat]

I wanted to add to my mod character the ability to gain sanity by hiding with the bush cap, but apparently I did the code wrong since I get this error, any help please?

Looks like the bushhat doesn't have a dapperness component on it. We know that both inst and components are there, otherwise it would have complained about those first, and because of Lua syntax, the last dot'ing would not produce a crash, since it is followed by an equals-sign, meaning it is being set to something (which also declares it, IIRC). Thus the conclusion, the bushhat doesn't have a dapperness component.
