TypeError: funcsMap[propKey] is not a function when using createText()

The code below works as expected with v2.0.0 of Restyle, but when I upgrade to v2.1.0 I get the following error.

TypeError: funcsMap[propKey] is not a function. (In 'funcsMap[propKey](props, {
  theme: theme,
  dimensions: dimensions
})', 'funcsMap[propKey]' is undefined)

After some digging through my code, it appears that if I remove my <Title> component, this error goes away. So there’s some issue with createText() perhaps?

I looked through the changelog for 2.0.0 → 2.1.0 but don’t see anything obvious? If I replace my <Title> component with a plain <Text> component, it also works (but of course I lose the Restyle features).

  forwardRef,
  useImperativeHandle,
  useRef,
  useState,

import { Theme } from '~/theme/index';

import TextInput from './TextInput';

const InputWrapper = createBox<Theme>();
const OuterWrapper = createBox<Theme>();
const OutlineView = createBox<Theme>();
const Wrapper = createBox<Theme>();
const Title = createText<Theme>();

const SignInTextInput = (
  {
    title,
    ...rest
  }: {
    onChangeText: () => void;
    title: string;
    value: string;
  },
  ref: React.Ref<any>,
) => {
  const [isFocused, setIsFocused] = useState(false);
  const inputRef = useRef<any>();

  const focusInput = () => {
    inputRef.current?.focus();
  };

  useImperativeHandle(ref, () => ({
    focus: () => {
      focusInput();
    },
  }));

  return (
    <TouchableWithoutFeedback onPress={focusInput}>
      <OuterWrapper>
        <OutlineView
          backgroundColor={
