JUnit test succeeded in IntelliJ, but failed in Maven

I wrote a JUnit test that runs successfully in Intellij and is passed. But if I run mvn clean test, that particular test fails. To be more specific, the challenge is to check whether the request has been sent or not. Therefore, when I run the test in IntelliJ, the test passes with status code 201 (successful). But when I run mvn clean install, it shows it as status code 400 (Bad request).

I searched the Internet about this, but could not find a solution. Please help me.

Below is the code. It does not work on the first statement assertEquals(response.getStatus(), Response.Status.CREATED.getStatusCode());::

@Test
public void testUpdateMultiValueAttributes() throws URISyntaxException {


    String createPayload =
            "{\n" +
                    " \"id\": 9,\n" +
                    " \"email\": \"" + "ismith@zzz.com" + "\",\n" +
                    " \"profile\": {\"userAttrs\":[" +
                    " {\"CUST_ATTR_MULTI_VALUE\": \"CUST_ATTR_MULTI_VALUE_3\"}" +
                    " ]}" +
                    "}";
    MockHttpRequest request = MockHttpRequest.put("/subscribers/9");
    request.contentType(MediaType.APPLICATION_JSON);
    request.content(createPayload.getBytes());
    MockHttpResponse response = new MockHttpResponse();
    dispatcher.invoke(request, response);
    LOG.error(response.getContentAsString());
    response.toString();


    assertEquals(response.getStatus(), Response.Status.CREATED.getStatusCode());
    SubscriberDto subscriber = null  ;
    try {

        subscriber = MarshallingUtils.unmarshallJSON(new TypeReference<SubscriberDto>() {
        }, response.getContentAsString());
    } catch (Exception e) {
        fail(e.getMessage());
    }

    Collection<SubscriberAttributeDto> customAttributes = subscriber.getProfile().getUserAttrs();

    if (customAttributes!=null)
    assertTrue(customAttributes.contains(new SubscriberAttributeDto("CUST_ATTR_MULTI_VALUE", "CUST_ATTR_MULTI_VALUE_3")));
