Creo un componente en la carpeta de widgets y lo importo a mi página de inicio principal (index.js)

Muestra error

 Error: Element type is invalid: expected a string (for built-in components) or class/function (for composite components) but got: undefined. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports.

El código del archivo principal es

 import { React, Component } from "react"; import axios from "axios"; import Style from "./widget-style/Notified.module.css"; import NotifiedModal from "../modals/NotifiedModal"; export default class GetNotified extends Component {}
