## Ask your question here
dubbo:3.1.1
jdk:11
os: centOS 7.6
配置如下:
```
dubbo:
application:
name:
metadata-service-protocol: tri
registry:
address: ${NACOS_REGISTER_ADDR}
group: ${DUBBO_REGISTER_GROUP}
parameters:
namespace: ${NACOS_NAMESPACE}
username: ${NACOS_USERNAME}
password: ${NACOS_PASSWORD}
metadata-report:
address: ${NACOS_REGISTER_ADDR}
protocol:
name: ${DUBBO_PROTOCAL_NAME}
port: ${DUBBO_PROTOCAL_PORT}
accesslog: false
consumer:
filter: dubboFilterConsumer
check: false
timeout: ${DUBBO_CONSUMER_TIMEOUT}
retries: ${DUBBO_CONSUMER_RETRIES}
provider:
filter: dubboFilterProvider
```
代码里面同时使用了rest和 tri 两种协议，直接注解在接口配置上
启动时一直报下面这个错误，
```

`dubbo.metadata-type: remote` 只是绕过了获取元数据的过程，如果可以的话还是希望能搭个 `dubbo.metadata-type: local` 的看下是什么问题

模块中同时使用了tri和rest协议是否这个原因导致？

已经解决了，在提供端加上dubbo.metadata-type: remote
怀疑是容器部署影响了元数据交换？目前没有找到具体的原因
