Adding headers when using MockMvcTarget

When using SpringRestPactRunner and MockMvcTarget the @TargetRequestFilter is never being invoked so I am not able to add headers. Is there another way? It looks like @TargetRequestFilter only works when using HttpTarget

@RunWith(SpringRestPactRunner.class)
@Provider("provider-name")
@PactBroker
public class PactVerificationTest {

    @Mock
    private MockedService mockedService;

    @InjectMocks
    private MyController controller = new MyController(mockedService);

    @TestTarget
    public final MockMvcTarget target = new MockMvcTarget();

    @Before
    public void before() {
        //initialize your mocks using your mocking framework
        MockitoAnnotations.initMocks(this);

        //configure the MockMvcTarget with your controller and controller advice
        target.setControllers(controller);
        target.setPrintRequestResponse(true);
    }

    // This block is never invoked
    @TargetRequestFilter
    public void requestFilter(HttpRequest request) {
        request.addHeader("Content-Type", MediaType.APPLICATION_JSON_VALUE);
    }

    @State({"person"})
    public void verify() throws DownstreamServiceException {
        target.setRunTimes(1);
        // ... mockito mocks
    }
}

Version 4.0.5 has been released with this change

I’ve added support for request filters, but the parameter will be an instance of MockHttpServletRequestBuilder not HttpRequest
