Root Cause

The server sent a response that is not a valid protobuf message, possibly due to a bug in the server's serialization or a corrupted network stream.

中文

服务器发送的响应不是有效的 protobuf 消息，可能是由于服务器序列化错误或网络流损坏。

Workarounds

  1. 85% success Check the server's protobuf version and regenerate code 
    protoc --go_out=. --go-grpc_out=. your.proto
  2. 80% success Enable gRPC max receive message size on the client 
    grpc.WithDefaultCallOptions(grpc.MaxCallRecvMsgSize(10*1024*1024))

Dead Ends

Common approaches that don't work:

  1. Ignore the error and retry with the same request 70% fail

    If the server has a bug, it will likely produce the same malformed response.

  2. Use a different protobuf library 40% fail

    The wire format is standard; the issue is likely in the server's generation.
