milvus proxy组件出现代理失败，日志信息如下，原因是什么？

我们的生产集群近期出现了一些proxy组件代理失败的告警，milvus集群版本是2.3.16，我检查了下proxy的日志，发现告警信息如下：

且三个proxy组件中，只有这一个组件有这个错误，询问了下业务方没有任何改动，能否帮忙分析一下这个报错的原因？

在milvus v2.3.5之后的版本中，传输协议里增加了对rpc调用权限的控制，比如这种：https://github.com/milvus-io/milvus-proto/blob/9ed8fb405005c2a2cdb10d30276d8bec9334b023/proto/milvus.proto#L140C23-L140C43

感觉像是客户端使用的sdk比较低，跟服务端的proto message定义不符。也许sdk版本低于2.3.5甚至2.2

could you make sure key is a string rather an int64?
should it be
key == 7226724665828788253
instead of
key == '7226724665828788253'
