request help: error reporting when deploying plug-ins in running mode

### Issue description

I use the official documents to deploy the go plug-in and mount the local address of the go runner into the docker. After starting apisix through the docker, I check the log and see that the plug-in execution fails.

My configured docker.yaml:
apisix:
image: apache/apisix:2.10.0-alpine
restart: always
privileged: true
volumes:
- ./apisix_log:/usr/local/apisix/logs
- ./apisix_conf/config.yaml:/usr/local/apisix/conf/config.yaml:ro
- /Users/yzy/Desktop/work/apisix-go-plugin-runner:/path/to/apisix-go-plugin-runner
depends_on:
- etcd
##network_mode: host
ports:
- "9080:9080/tcp"
- "9091:9091/tcp"
- "9443:9443/tcp"
- "9092:9092/tcp"
networks:
apisix:

External plug-in configuration in apifix configuration:
ext-plugin:
cmd: ["/path/to/apisix-go-plugin-runner/go-runner", "run"]
