Vue + Jest Не могу прочитать свойство 'default' из неопределенного

Question

Я получаю эту ошибку, и я не знаю, что ее вызывает.
TypeError: Невозможно прочитать свойство 'default' из неопределенного
Я начал возиться с тестами сейчас, если ошибка глупая, я извиняюсь

Приложение. vue

Я взял этот пример из vue -test- Страница утилит, это самый простой c пример example.spe c. js

import { mount } from '@vue/test-utils'
import main from '@/App.vue'

describe('Component', () => {
  test('is a Vue instance', () => {
    const wrapper = mount(main)
    console.log(wrapper)
    expect(wrapper.isVueInstance()).toBeTruthy()
  })
})

Если кто-то может помочь мне найти мою ошибку, я был бы очень признателен.
