I answer my own question. The fix is fairly simple. Open App.js file and modify this line class YourApp extends Component { into export default class YourApp extends Component<{}> {

Hi smithaitufe, You are having the issue because you are probably exporting addNewTask as default and you importing it as named export. So change import {addNewTask} from ‘…/actions’; to import addNewTask from ‘…/actions’;
