一、如果你也发生这个问题，请看看你的registry.conf   config有没有配，在最下面。。。。。。。

二、项目中的seata.registry.nacos配置没有配置namespace

 

 源码：

 我的入参是：

"app" -> "unknown"
"healthyOnly" -> "false"
"namespaceId" -> "public"
"clientIP" -> "ip.ip.ip"
"serviceName" -> "SEATA_GROUP@@serverAddr"
"udpPort" -> "58796"
"accessToken" -> "eyJhbGciOiJIUzI1NiJ9.eyJzdWIiOiJuYWNvcyIsImV4cCI6MTYzNTg3NDE1MH0.OzlhcgRwfIwmbXLPZjYoxog988utcJ_7TVOwUAuxLM0"
"clusters" -> "default"

namespace 一直是public.....所以想到了是参数问题。我的seata版本是1.4.2 

分析源码请看这篇文章---版本有些老，但是可以看看思路，最后找到入参即可看到问题原因。
