Regression in 0.1.3 with figure caption

This code

#import "@preview/lemmify:0.1.3" : *
#let (theorem, rules) = default-theorems("thm-group")
#show: rules
#theorem[Theorem content goes here.]

gives the error

error: cannot access fields on type none
   ┌─ @preview/lemmify:0.1.3/src/util.typ:25:16

Which is probably wrong unless I'm missing something. Perhaps if should be if figure.has("caption") { figure.caption.body }?

(This reached me via web app feedback.)
