The Lambda runtime receives an event as a JSON-formatted string and converts it into an object. However, the following seems to work just fine: Setting const setTheme = jest.fn() didn't work ‍♂️, @matchatype If the problem in your #8475 (comment) is like #8166 that deep-equality matchers compare functions according to referential identity, then we recommend asymmetric matcher as expected value, see https://jestjs.io/docs/en/expect#expectanyconstructor.
