How to fix unit test Missing Method Invocation Exception?

Question

When I run the test it shows the given error which I gave below.

It shows Missing Method Invocation Exception Error. But I use that method in that test.

I use Mockito to inject mockito.

If anyone can solve this please help me.

Entity

public class VesselInfo {

    private Long vesselId;

    private String ownerName;
}

Service

@Service
public class VesselService {
    public List<VesselInfo> prepareMockVesselList(){
    
            List<VesselInfo> vesselMockDataList = new ArrayList<>();
            VesselInfo vesselInfo = new VesselInfo();
            vesselInfo.setVesselId(1L);
            vesselInfo.setOwnerName("Abdul Malek");
    
    }
    public List<VesselInfo> findVesselByOwnerNid(String ownerNid){
            List<VesselInfo> vesselMockDataList = new ArrayList<>();
            vesselMockDataList = prepareMockVesselList();
            List<VesselInfo> result = new ArrayList<>();
            for(VesselInfo vesselInfo : vesselMockDataList){
                if(vesselInfo.getOwnerNID().equals(ownerNid)){
                    //return vesselInfo;
                    result.add(vesselInfo);
                }
            }
            return result;
        }
 }

Test

@SpringBootTest(classes = SurveyServiceTest.class)
public class VesselServiceTest {

    @InjectMocks
    VesselService vesselService;
    @Test
    public void findVesselByOwnerNidTest(){

        // with valid Nid
        List<VesselInfo> vesselInfoList = new ArrayList<>();
        VesselInfo vesselInfo = new VesselInfo();
        vesselInfo.setOwnerNID("12341654565");

        VesselInfo vesselInfo1 = new VesselInfo();
        vesselInfo1.setOwnerNID("455454455");


        vesselInfoList.add(vesselInfo);
        vesselInfoList.add(vesselInfo1);


        when(vesselService.findVesselByOwnerNid("12341654565")).thenReturn(vesselInfoList);

    }
}
