I uncounted the same err. I import the remark-slate with: `const slate = require('remark-slate');` Then resolve the error with: ``` unified() .use(remarkParse) .use(slate.default) ```

This is probably caused by the onKeydown/up event handling for CJK. Recently, I fixed a similar issue in my project using onKeyPressed event instead of onKeyDown/up.
