遇到同样问题，求解决方案。dubbo-admin 0.5.0+ dubbo3.1.8 + zookeeper。
dubbo admin的注册信息跟dubbo的应用级注册信息在同级下，解析出错。
@fffguo 试了下可以增加dubbo.registry.parameters.rootPath=${group}/services规避，理解是为应用级注册信息再增加一层级，admin不会为group后的第二级添加配置，所以就不会出问题了

好的，感谢回复，我尝试一下试试
@fffguo 试了吗 可以吗 我这边也是使用分组后，一启动 dubbo-admin 就报Caused by: com.fasterxml.jackson.core.JsonParseException: Unexpected character ('.' (code 46)): Expected space separating root-level values at [Source: (byte[])"127.0.0.1"; line: 1, column: 7]
