java.lang.IllegalArgumentException：在反序列化JSON提要时，使用OdatajClient

在反序列化JSON提要时，我不断遇到java.lang.IllegalArgumentException:

每当我在JUnit测试中运行此函数时。你知道是什么导致了这个问题吗

public ODataEntity getInvoicedOrderDetails(Long orderNumber) {

ODataURIBuilder uriBuilder = new ODataURIBuilder(serviceRootUri).appendEntitySetSegment(orders).top(3);

    ODataEntitySetRequest req = ODataRetrieveRequestFactory.getEntitySetRequest(uriBuilder.build());
    req.setFormat(ODataPubFormat.JSON);

    ODataRetrieveResponse<ODataEntitySet> groupResult = req.execute();
    ODataEntitySet result = groupResult.getBody();
    ODataEntity res = result.getEntities().get(0);
    return res ;
}

如果你能发布完整的堆栈跟踪，那就太好了。只是添加了它。有什么想法吗？检查内部异常。
