It looks like your project is working just fine, but in order for it to pass the tests, you have to use separate .get() functions for requests with parameters and requests without.

You will need to create the ‘/api/timestamp/’ endpoint separately from the endpoint that reads the date to be parsed from the URL. You won’t need a conditional to deal with this endpoint.
Hope it helps!
