MainPage에 소개하기 버튼을 만들어 AboutPage로 넘어가는 부분에서 오류가 발생합니다.

혹시나 제가 만든 것이 문제가 있는건가 하여 강사님꺼를 복붙을 하였는데도 오류가 발생합니다.

The action 'NAVIGATE' with payload {"name":"AboutePage"} was not handled by any navigator.

Do you have a screen named 'AboutePage'?

If you're trying to navigate to a screen in a nested navigator, see https://reactnavigation.org/docs/nesting-navigators#navigating-to-a-screen-in-a-nested-navigator.

This is a development-only warning and won't be shown in production.
