Element type is invalid: expected a string (for built-in components) or a class/function

Question

import React from \'react\';
import ReactDOM from \'react-dom\';
import Map from \'./components/map/container/map\';
import App from \'./App\';
import \'./index.css\         


        

Answer 1

For me, I faced this issue when I forget to use react-redux's connect in my export.

So,

changing:

 export default(mapStateToProps, mapDispatchToProps)(ContentTile);

To:

export default connect(mapStateToProps, mapDispatchToProps)(ContentTile);

solved the issue. Really silly mistake
