这个报错可能是什么原因呢？另外这里可以直接用passthrough替换cluster 'original_dst_cluster'吗？

hello. 目前我也在尝试用envoy作为global-sidecar的poc，目前遇到流量到global-sidecar后无法分发到正确des的问题。

lua添加上去就是为了解决这个短域名问题

@YonkaFang 我们可以先合入

一些chart的调整以及使用的调整，我来跟进

用 envoy 替换的 gs 的方案，有计划支持 mtls 流量吗

感谢回复，这个问题已经解决了。另外想请问下，用 envoy 作为 gs 的方案有计划支持 mtls 流量吗？
