Methods and Unit tests fine but validation test fails

I modified the method GetMoviesByGenreAsync it gives me wanted result but i didn’t understand what to do next ?

GetMoviesByGenre and TestReturnsMoviesByDefaults test in MoviesRespositoryTests.cs are working

but when i start the project and click paging button in status page it says “Paging: Did not receive the proper response when paging by genre”.

i don’t want answers , i just don t get what is expected from me , i am stuck

Any guide or help pls

i was disabled the sort stage , when i activate it, validation test worked too.
