Root Cause

The server has registered the service but not this specific method. Typically caused by an outdated generated server stub or a client using a newer proto than the server.

generic

中文

服务端已注册该服务但未注册此特定方法。通常由过时的生成服务端 stub，或客户端使用比服务端更新的 proto 引起。

Workarounds

  1. 95% success 
    protoc --go_out=. --go-grpc_out=. user.proto
go build ./...
  2. 90% success 
    grpcurl -plaintext localhost:50051 describe pb.UserService

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The method handler must exist as a generated function; string manipulation on descriptors does not register a callable handler

  2. 70% fail

    The older method may not exist either; the correct fix is aligning proto versions
