Модуль не найден в Heroku Deploy, но найден в локальной сети

Question

Поэтому я попытался развернуть свое приложение в Heroku и обнаружил эту ошибку Module not found: Error: Can't resolve './components/add-credentials/AddEducation' in '/tmp/build_6b46c3e828c5afc20e70a4b1b2232f69/client/src'

Все отлично работает, включая этот модуль в localhost.Что я должен изменить, чтобы это работало?
