Реакция навигации: объект 'навигация' еще не был инициализирован

Question

Я обновляю библиотеку React Navigation с 4.xx до 5 через https://reactnavigation.org/docs/en/upgrading-from-4.x.html и https://reactnavigation.org/docs/en/compatibility.html.

Я получаю ошибку:

NavigationDebug Error:  Error: The 'navigation' object hasn't been initialized yet. This might happen if you don't have a navigator mounted, or if the navigator hasn't finished mounting. You can ensure that all navigators have mounted after the callback to 'useEffect' is called in your root component. See https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html#handling-initialization for more details.

при создании NavigationService (https://reactnavigation.org/docs/en/navigating-without-navigation-prop.html).

index. js

let Init = ((props) => {

    enableScreens();

    React.useEffect(() => {
        isMountedRef.current = true;

        return () => isMountedRef.current = false;
    }, [])

    return (
        <NavigationContainer ref={navigationServiceRef}>
            <Provider {...stores}>
                    <App {...props}/>
            </Provider>
        </NavigationContainer>
    );
})

AppRegistry.registerComponent(appName, () => Init);

NavigationService

import { NavigationActions, StackActions } from '@react-navigation/compat';

import React from 'react';

export const isMountedRef = React.createRef();

export const navigationServiceRef = React.createRef();

export function navigate(name, params) {
    if (isMountedRef.current && navigationServiceRef.current) {
        console.log("Navigation Should happen")
        try {
            navigationServiceRef.current.navigate("App", params);
        }catch(e){
            console.log("NavigationDebug Error: ", e)
        }
    } else {

    }
}

export default {
    navigate
};
