### Pre-check - [X] I am sure that all the content I provide is in English. ### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dubbo/issues?q=is%3Aissue) and found no similar issues. ### Apache Dubbo Component Java SDK (apache/dubbo) ### Dubbo Version 3.2.15 ### Steps to reproduce this issue Start a dubbo provider service register by rest protocol with config version or group In my case the register log is on below ``` 2024-08-13T17:03:56.633+08:00 INFO 31907 --- [springboot-dubbo-provider] [ main] o.a.d.r.zookeeper.ZookeeperRegistry : [DUBBO] Register: rest://198.19.249.3:8080/com.doodl6.springboot.dubbo.api.FirstDubboService?application=springboot-dubbo-service-local&deprecated=false&dubbo=2.0.2&dynamic=true&generic=false&interface=com.doodl6.springboot.dubbo.api.FirstDubboService&methods=getDubboInfo&prefer.serialization=fastjson2,hessian2&release=3.2.15&revision=1.0-local&server=netty&service-name-mapping=true&side=provider&timeout=10000×tamp=1723539836485&version=1.0-local, dubbo version: 3.2.15, current host: 198.19.249.3 ``` Then, start a another consumer service to invoke the service use rest protocol. By default, dubbo will use okhttp to send http request, After send the request, here is the provider service's log ``` POST /dubbo-rest/getDubboInfo HTTP/1.1 Host: 198.19.249.3:8080 User-Agent: okhttp/4.12.0 Content-Length: 8 Accept: application/json; charset=UTF-8 Accept-Encoding: gzip Content-Type: application/json Rest-Service-Path: com.doodl6.springboot.dubbo.api.FirstDubboService Rest-Service-Remote.application: springboot-web-local Rest-Service-Version: 1.0-local, dubbo version: 3.2.15, current host: 198.19.249.3, error code: .
