InternalServerError:处理此请求时发生未知服务器错误

Question

我在调用CosmosDatabase.createContainerIfNotExists.时偶尔收到Azure CosmosDB模拟器的以下错误

• 此外，如果错误消息包含许多无助的细节，则无法理解原因。如何从Azure CosmosDB模拟器获取有关该错误的更多信息？

• 错误的原因是什么？如果出现错误，现有容器的计数大约为70到130。对于250个集装箱的限制来说，这应该没有问题。

• 对错误的最佳处理方法是什么？

Answer 1

错误–

已抑制：java.lang.Exception:#块终止，出现错误

如果您面临块终止错误。您应该在进行api调用时创建一个新连接。这将解决问题。

我建议你提高支持票

您也可以参考CosmosDatabase.createContainerIfNotExists 的GitHub回购

Answer 2

我在启动时初始化对象时已经尝试创建容器，从而解决了这个问题。在这一点上我忽略了一个错误。这种初始化在很大程度上是按顺序进行的。

稍后使用容器时，如果之前失败，我会重试。这稍微减少了应用程序的启动时间，但错误不再发生。
