Mockito Junit5 NullPointerException - mocking public interface

Question

Java Class

public class SendNotification {

    public  NotificationProperty config;
    public  PostDbClient postDbClient;
    public  ObjectMapper objectMapper;
    public  AmazonSNS snsClient;
    public  NotificationParser notificationParser;
}

Test Class

@ExtendWith(MockitoExtension.class)
public class SendNotificationTest {

    @Mock
    AmazonSNS amazonSNS;

    @Mock
    public  NotificationProperty config;

    @Mock
    public  PostDbClient postDbClient;

    @Mock
    public  ObjectMapper objectMapper;

    @Mock
    public  NotificationParser notificationParser;


    @InjectMocks
    SendNotification sendNotification;

    @BeforeEach
    public void createMocks() {
       // MockitoAnnotations.openMocks(this);

    }

    @Test
    public void shouldSendNotification() {

        System.out.println("Step1");
        System.out.println(config);
        System.out.println("Step2");
        System.out.println(postDbClient);
        System.out.println("Step3");
        System.out.println(objectMapper);
        System.out.println("Step4");
        System.out.println(notificationParser);
        System.out.println("Step5");
        System.out.println(amazonSNS);
        System.out.println("Step6");
        Mockito.when(amazonSNS.publish(any())).thenReturn(new PublishResult());
        // doReturn(new PublishResult()).when(amazonSNS).publish(new PublishRequest());
       
    }

Dependencies

        springBootVersion = '2.7.7'

        testImplementation group: 'io.springfox', name: 'springfox-staticdocs', version: '2.6.1'
        testImplementation 'org.junit.jupiter:JUnit-jupiter:5.6.2'
        testImplementation 'org.mockito:mockito-inline:5.0.0'

test {
    useJUnitPlatform()
    dependsOn cleanTest
    testLogging.showStandardStreams = true
    maxParallelForks = 1
}

I am not able to mock any public interface in my whole spring boot project. Test Case in passing in intelij, failing while running gradle clean buid
