How remove unnecessary Mockito stubbings error

Question

@Test
public void testWhenCorrectRequestPassedToUpdateCasaApplicationForIncomeUpdate() throws InvalidEventException {

    when(requestMapper.map(getApplicationUpdateRequestForIncome())).thenReturn(getCasaApplicationData());
    when(service.updateApplication(any())).thenReturn(getResultApplicationStatus());
    when(responseMapper.updateMap(any())).thenReturn(getUpdationResponse());

    Result<ApplicationUpdationResponse> response = casaApplicationHandler
            .updateCasaApplication(getApplicationUpdateRequestForIncome());

    assertNotNull(response);
    assertTrue(response.isSuccess());

}
