Dynamics crm 当MS dynamics返回http/1.1500内部服务器错误时，如何检索http响应正文？

我正在使用Olingo客户端连接到Microsoft Dynamics 365 V9.0，以更新帐户等实体

但是，Olingo客户端（最新版本4.4.0）会不时返回ODataServerErrorException，仅返回服务器状态，如“HTTP/1.1500内部服务器错误”。这并不能说明很多根本原因。我们需要的是http响应体返回的详细错误消息。 代码段和堆栈跟踪如下所示：

try {
        ODataBatchResponse response = batchManager.getAsyncResponse().get(2, TimeUnit.MINUTES)
        ...
} catch (Exception e) {
   log.error("error: "+ e.getMessage(), e)
}

堆栈跟踪：

您正在使用Web Api端点吗？我想说您的安全令牌已过期，但这将是一个错误。既然是500，问题就在于动力学。如果您有请求正文和标题，您应该打开一个票证

您以前是否运行过v8.2？这有助于缩小问题的范围。

Thx Nick！打开httpclient日志记录后，捕获错误消息：{“消息”：“服务器正忙，请求未完成。请稍后重试。”，…}。问题是如何在运行时获取消息并将其呈现给调用方。
