Can't import the named export 'createContext' from non EcmaScript module

My code:
```
ReactDOM.render(
  <UserbackProvider token="3746|70482|oTIFCuaXR4Kc6kzJ5hCX61icLQeoOCrwmp4tkazp0Ufq0byH4k">
    <Provider store={store}>
      <App />
    </Provider>
  </UserbackProvider>,
  document.getElementById('root'),
);
```
