code

const formatX = (value) => {
  'worklet'; // <-- this line caused error!
  return value.length ? `${new Date(parseInt(value)).toLocaleDateString()}` : '';
}

error

TypeError: undefined is not a function, js engine: hermes

package.json

"@babel/core": "^7.12.9",
"react": "17.0.1",
"react-native": "0.64.0",
"react-native-reanimated": "^2.1.0",
"metro-react-native-babel-preset": "^0.64.0",

babel.config.js

module.exports = {
  presets: ['module:metro-react-native-babel-preset'],
  plugins: [
    ["@babel/plugin-proposal-decorators", { "legacy": true }],
    'react-native-reanimated/plugin',
  ],
};

Downgrade react-native to 0.63.0 resolves the issue though, but it took quite some time for me to upgrade the whole project to 0.64.
