[GitHub] [dubbo] weii918 opened a new issue, #10848: Dubbo 升级 2.7.18 后，泛化调用异常
weii918 opened a new issue, #10848:
URL: https://github.com/apache/dubbo/issues/10848
<!-- If you need to report a security issue please visit https://github.com/apache/dubbo/security/policy -->
- [ ] I have searched the [issues](https://github.com/apache/dubbo/issues) of this repository and believe that this is not a duplicate.
### Environment
* Dubbo version: 2.7.18
* Operating System version: xxx
* Java version: 1.8
### Steps to reproduce this issue
1. dubbo 从 2.7.8 升级至 2.7.18
2. 泛化调用异常：Failed to invoke the method $invoke in the service org.apache.dubbo.rpc.service.GenericService. No provider available for the service XXXXX，检查了 zookeeper 服务是注册上去的
3. 泛化调用代码如下：
```
ReferenceConfig<GenericService> referenceConfig = this.referenceConfigFactory.generate();
referenceConfig.setInterface(interfaceName);
if (StringUtils.isNotEmpty(group)) {
referenceConfig.setGroup(group);
}
if (StringUtils.isNotEmpty(version)) {
referenceConfig.setVersion(version);
}
referenceConfig.setGeneric("true");
referenceConfig.setCheck(false);
referenceConfig.setTimeout(CONSUMER_TIMEOUT);
genericService = referenceConfig.get();
genericService.$invoke(methodName, paramTypes, paramValues)
```
Pls. provide [GitHub address] to reproduce this issue.
### Expected Behavior
<!-- What do you expect from the above steps？-->
正常调用
<!-- What actually happens? -->
If there is an exception, please attach the exception trace:

检查服务注册是否加上了 dubbo.provider.tag 配置，服务调用方也同样要带上 tag。这个在 2.7.8 调用方不带 tag 是可以调用注册带有 tag 的服务的，2.7.18 修复了。还有就是 2.7.18 的泛化调用过滤器GenericFilter做了修改，如果重写了过滤器可以对照官方的修改。
