Just Randomly Solved this after 3 match in valorant The main problem comes from this line of code

val mainViewModel = MainViewModel(storyRepository) 

That initiated before

Mockito.when(storyRepository.getSession()).thenReturn(dummyFlow) Mockito.when(storyRepository.getStoriesWithPaging(dummyToken)).thenReturn(expectedQuote)

Which creates the non-null error
