VDM 调用函数 import returns null 而不会抛出异常

Question

我正在使用 VDM 查询函数导入。它 returns null，这不是预期的。它不会进入异常流程，因此无法确定调用是否成功。

    PurchaseRequisitionHeaderBOView resultPojo = null;
    try {
        resultPojo = sspprService.purchaserequisition_WdActivation(purchaseRequisition, draftUUID, isActiveEntity)
                .execute(new ErpConfigContext(s4destination));
        if (resultPojo == null)
            logger.error("VDM call returned null!");
    } catch (ODataException e) {
        logger.error(EXCEPTION_ACTIVATING_CART, e);
        throw new org.apache.olingo.odata2.api.exception.ODataException(EXCEPTION_ACTIVATING_CART, e);
    }

预期：如果调用成功非空 POJO。如果调用失败，它应该命中 catch 块。

请将 SAP Cloud SDK 的依赖项更新为 3.6.0，因为它 fixes the issue of parsing OData function import responses。不再需要定制。如果它适合你，请告诉我。
