Details

Our current project is upgrading from version 2.6.2 of dubbo. The system accessed normally in versions 2.7.3 and below.When upgrading to version 2.7.4.1 and above, inter-service calls within the system started encountering this exception.

1. The gateway makes a generalized call to Service A, and Service A responds normally. The gateway makes a generalized call to Service B, and Service B also responds normally.

2. The gateway makes a generalized call to Service A, and within Service A, it internally calls Service B. When calling Service B, the metadata is similar to.

methodName: querySimple2
serviceKey: com.xx.B.service.xx
parameterType: com.xx.B.bean.xx

3. When calling Service B, there is an error "Service not found: com.xx.A.service.xx". This service name is the name of the calling party and is not in the metadata.During debugging, it was found that the decode method is obtaining an incorrect path, com.xx.A.service.xx, which is not among the services exposed by the current service.

Is there anyone who can help me look at this issue? Since we have tested from version 2.7.4.1 to 2.7.23 and encountered this problem, it might not be a bug but rather a misconfiguration on our part.
