Not enough info to help you with this. If you haven't sorted this yet please open a new issue with steps to reproduce / code samples / etc.

FYI first result on Google for "TypeError: this.updater.enqueueCallback is not a function" is facebook/react#10320. Are you sure you aren't somehow including React 15 and React 16?

We're waiting for formsy-react to support React 16 before we can state that we're compatible with React 16.
