Testing Unirest with PowerMockito

I want to test a method that sends a get request to a server using Unirest

I have used PowerMockito and Mockito to test some methods, but when I try to do it on the method below, I get null pointer exception.

This is the method I want to test:

public HttpResponse<JsonNode> jsonRequest(String path) {
        HttpResponse<JsonNode> jsonResponse = null;
        try {
            jsonResponse = Unirest
                    .get(path)
                    .header("accept", "application/json")
                    .asJson();
        } catch (UnirestException e) {
            System.out.println("Server is unreachable at the moment. Please try again later");
        }
        return jsonResponse;
    }

And this is the test case:

@RunWith(PowerMockRunner.class)
@PrepareForTest(Unirest.class)

public class TestModel {

    @Mock
    private GetRequest getRequest;

    @Mock
    private HttpResponse<JsonNode> httpResponse;

    @InjectMocks
    DatabaseModel databaseModel;

    @Test
    public void testController() {
        PowerMockito.mockStatic(Unirest.class);
        JsonNode jsonNode = mock(JsonNode.class);
        when(Unirest.get("12345")).thenReturn(getRequest);
        when(getRequest.asJson()).thenReturn(httpResponse);
        when(httpResponse.getStatus()).thenReturn(200);

        assertEquals(200, databaseModel.jsonRequest("12345").getStatus());
    }

So I expect to get 200 (Or any status\body I will decide on) But for some reason I get java.lang.NullPointerException which directs me to this line:

.asJson();

in the getRequest.

Thanks in advance
