使用接口文档功能的时候会出现 may be version or group mismatch 问题

服务端dubbo 是2.7.7 的版本，使用的dubbo admin 是3.0.2的版本

接口文档功能在请求服务端的时候会出现may be version or group mismatch 错误，请问哪个版本是支持2.7.7的

Start by reproducing the interface-documentation request with Dubbo server 2.7.7 and Dubbo Admin 3.0.2, recording where the “may be version or group mismatch” error appears. Trace the compatibility handling for the interface-documentation feature and determine which server and admin versions are supported together; the issue is done when the supported combination is confirmed or the mismatch is resolved.
