Root Cause

Client's proto definition is outdated and doesn't include a field that the server sends.

generic

中文

客户端的 proto 定义过时，未包含服务器发送的字段。

Workarounds

  1. 100% success 
    Run protoc with the latest .proto file to update the generated Go code.
  2. 60% success 
    decoder := protojson.UnmarshalOptions{DiscardUnknown: true}; err := decoder.Unmarshal(data, msg)

Dead Ends

Common approaches that don't work:

  1. 80% fail

    gRPC by default ignores unknown fields, but this error suggests strict parsing is enabled.

  2. 90% fail

    Incorrect field number can cause data corruption.
