react-i18next: TypeError: Cannot read property 'ready' of null

I am trying to follow this example but getting this error:

react-i18next: ^8.1.0 i18next: ^12.0.0 react-native: ^0.57.0

This is a code snippet from my App.tsx:

const WrappedAppNavigator = ({ t }) => <AppNavigator screenProps={{ t }} />;
const ReloadAppOnLanguageChange = withNamespaces('translation', {
	bindI18n: 'languageChanged',
	bindStore: false,
})(WrappedAppNavigator);

export default class App extends Component<Props, State> {

    render() {

        if (this.state.isLoading) {
	    return (
		<View style={styles.container}>
			<Text>Loading ...</Text>
		</View>
	    );
	}

        return (
            <Provider store={this.state.store}> {/*import { Provider } from 'react-redux';*/}
                <Root> {/* native-base */}
	            <ReloadAppOnLanguageChange screenProps={{ notifService: this.notifService, store: this.state.store }} />
                </Root>
           </Provider>
        );
    }
}
