Root Cause

The server does not implement the requested RPC method, possibly due to outdated proto generation.

generic

中文

服务器未实现请求的 RPC 方法，可能是由于 proto 生成过时。

Workarounds

  1. 95% success 
    protoc --go_out=. --go-grpc_out=. *.proto; go build -o server server.go
  2. 90% success 
    if err := pb.RegisterGreeterServer(s, &server{}); err != nil { log.Fatal(err) }
  3. 85% success 
    Ensure method name matches exactly: client.SayHello(ctx, req)

Dead Ends

Common approaches that don't work:

  1. Trying other methods that also don't exist. 80% fail

    All methods may be unimplemented.

  2. Using nil response from failed call. 90% fail

    Nil pointer dereference.

  3. Assuming the method was removed. 60% fail

    May still be needed.
