SyntaxError: Named export 'convert' not found. The requested module 'unist-util-is' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:
import pkg from 'unist-util-is';
const {convert} = pkg;
