使用嵌套对象的RestAssured Post调用会抛出错误“java.lang.AssertionError：1 expectation failed。预期状态代码＆lt; 200＆gt;但是＆lt; 500＆gt;。“

Question

@Test
public void testPost() throws URISyntaxException {
    DbConnectionProperties sourceDB = new DbConnectionProperties("SourceDBName", "SourceDBDriver", "SourceDBUrl", "SourceDBUserName", "SourceDBPassword");
    DbConnectionProperties destinationDB = new DbConnectionProperties("DestinationDBName", "DestinationDBDriver", "DestinationDBUrl", "DestinationDBUserName", "DestinationDBPassword");
    Streams streamsAvailablity = new Streams(1, 1, 1, 1);

    AgencyRequest agencyRequest = new AgencyRequest();
    agencyRequest.setConnectorId(1);
    agencyRequest.setJobConfig("/usr/local/workspace/test.config.xml");
    agencyRequest.setConnectorName("/usr/local/workspace/test.kjb");
    agencyRequest.setRequestId(1);
    agencyRequest.setTenantId(1);
    agencyRequest.setTenantName("Test Tenant");
    agencyRequest.setTimeZone("UTC");
    agencyRequest.setSourceDB(sourceDB);
    agencyRequest.setDestinationDB(destinationDB);
    agencyRequest.setIntervalBatchUnit("d");
    agencyRequest.setIntervalBatch(0);
    agencyRequest.setIntervalReloadUnit("d");
    agencyRequest.setIntervalReload(0);
    agencyRequest.setMustUseBatch(1);
    agencyRequest.setStreamsAvailablity(streamsAvailablity);

    String json = new Gson().toJson(agencyRequest);
    System.out.println(json);
    System.out.println(uri + "/" + ResourceConstants.JOB_CONFIG);
    given().
    accept(ContentType.JSON).
    contentType(ContentType.JSON).
    body(json).
    post(new URI(uri + "/" + ResourceConstants.JOB_CONFIG)).
    then().
    assertThat().
    statusCode(HttpStatus.OK_200);
}

当我使用嵌套对象传递json正文时，它会向我抛出一个内部错误＆＃34; 状态代码500 ＆＃34;如果我传递没有嵌套对象的json字符串

，它会成功
