> > `dubbo-3.2.10.jar`好像默认不会自动加载系统的这些`Filter` > > 这个和设计是不符合的，你是怎么发现的。有没有配置 filter 这个参数 有配置 filter 参数，但参数里定义了自定义的Filter实现，没有设置框架层面实现的Filter。`dubbo-3.1.1`都不会报异常，升级到`dubbo-3.2.10`后，消费者通过P2P方式请求元数据信息时，就报这个异常。 【案例-1】 Failed to get app metadata for revision 6dd35818cdc09f4b682f8ac3fe312847 ``` 2024-01-23 11:51:14,075 [Dubbo-framework-metadata-retry-thread-1] ERROR org.apache.dubbo.registry.client.metadata.MetadataUtils - [DUBBO] Failed to get app metadata for revision 6dd35818cdc09f4b682f8ac3fe312847 for type local from instance xxx.xxx.xxx.xxx:8504, dubbo version: 3.2.9, current host: xxx.xxx.xxx.xxx, error code: 1-39.
