showWithReviews test case breaks if submittedDate is added

[richardcresswell]

If you change this line to

.reviews().submittedDate()

The ObjectMapper cannot deserialize the date.

Error deserializing data from '{"data":{"shows":[{"title":"mock title","reviews":[{"submittedDate":"2021-04-15T11:37:22.424887-04:00","username":"DGS User","starScore":5},{"submittedDate":"2021-04-15T11:37:22.424953-04:00","username":"DGS User 2","starScore":3}]}]}}' with JsonPath 'data.shows[*]' and target class java.util.List<com.example.demo.generated.types.Show>
