Карма терпит неудачу, возвращает ОШИБКУ без подробностей

У меня есть угловой проект CLI, который использует Angular + Karma + Mocha. Когда я запускаю ng test, исходный код транспилируется, сервер запускается, открывается браузер, а затем появляется ошибка ниже.

• Кто-нибудь видел подобную ошибку и может дать совет, как получить больше информации из кармы? Цель состоит в том, чтобы получить достаточно информации для устранения ошибки.

Дополнительный контекст

• Приложение работает, как и ожидалось, с ng serve
• Я поменял тестовый раннер на wallabyJS, и тесты выполняются, как и ожидалось.
• Запуск Karma без angular CLI имеет тот же результат, что и ng test
• Удалил node_modules согласно удалить решение node_modules

Кажется, что это полностью неверная конфигурация кармы.
