Hi, This error costed me a hackathon win !

basically at picker.web.js , it's not able to import createElement. if you go and check picker.web.js file createElement is used something like this.

const createElement = ReactNativeWeb.createElement || ReactNativeWeb.unstable_createElement; 

we just need unstable_createElement ! so comment out this line and add following to the imports. !

import { unstable_createElement as createElement } from 'react-native-web'; 

now export your web builds !
