Root Cause

A string field in the proto message contains invalid UTF-8 bytes, which violates proto3 string requirements.

generic

中文

proto 消息中的字符串字段包含无效的 UTF-8 字节，违反了 proto3 字符串要求。

Workarounds

  1. 90% success 
    req.Name = strings.ToValidUTF8(req.Name, "")
  2. 50% success 
    marshaler := protojson.MarshalOptions{EmitUnpopulated: true}; data, _ := marshaler.Marshal(msg)

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Changing field type requires proto regeneration and may break compatibility.

  2. 100% fail

    The marshaling will fail and the RPC will not complete.
