Workarounds

  1. 90% success Regenerate the server stub from the .proto file and implement the missing RPC method. Example: `protoc --go_out=. --go-grpc_out=. myapp.proto` then add the method handler.

中文步骤

  1. Regenerate the server stub from the .proto file and implement the missing RPC method. Example: `protoc --go_out=. --go-grpc_out=. myapp.proto` then add the method handler.
  2. Check that the server binary has been recompiled with the latest proto definition and deployed correctly.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    The method is still missing from the server's implementation.

  2. 70% fail

    The client expects a valid response; empty responses may cause downstream errors.
