@bang9 실행하면 에러가 나는데 어떤 설정이 필요한걸까요?

➜  chat-ai-widget git:(test/AC-4551-add-unit-tests) ✗ yarn test-ct
Error: /Users/liam.cho/Github/chat-ai-widget/__visual_unit_tests__/tests.spec.tsx: Couldn't find a Program

    at e.getProgramParent (/Users/liam.cho/Github/chat-ai-widget/node_modules/playwright/lib/transform/babelBundleImpl.js:12:40826)

edit:
원인을 찾았습니다. 아래 두개가 충돌이 있는것 같습니다

    "@playwright/experimental-ct-react": "^1.49.1",
    "@playwright/test": "^1.48.1",

@playwright/test 를 지우고 install 하면 잘 돕니다. 그래서 둘중 하나는 포기해야만 하는 상황인것 같습니다. 현재는 @playwright/test 로 e2e 테스트를 돌리고 있기 때문에 unit test 를 포기해야 할 것 같습니다..
