我在AssertionError: expected [Function] to be a function尝试异步函数是否引发错误时遇到此错误
it('has invalid password', async () => {
const fakeData = { email: userData.email, password: 'something but not the password!.' }
expect(async () => { await authService.authenticate(fakeData) }).to.throw(errors.UnauthenticatedError)
})
结果：
AssertionError: expected [Function] to be a function

我做错什么了？
