[GitHub] [dubbo] linsida1 opened a new issue #8244: Dubbo 3.0 Triple consumer throws NPE
linsida1 opened a new issue #8244:
URL: https://github.com/apache/dubbo/issues/8244
when calling the dubbo method, service failed with the below exception. I use the dubbo 3 with triple protocol.
Could any one tell me why the rpc calling failed?
When I debug the code, I found consumer can find the provider successfully, but the RpcServiceContext consumerUrl is null.
The detail log as below:
