根因分析

proto2 消息中存在必填字段，在序列化前未赋值。proto3 已移除 required，但 proto2（及部分迁移中的 schema）仍强制校验。

English

A proto2 message has a required field that was not populated before marshaling. proto3 removed required, but proto2 (and some migrated schemas) still enforce it.

generic

解决方案

  1. 90% 成功率 
    Populate required fields before marshal, or migrate the schema to proto3:
msg := &pb.User{Id: userID, Name: name}
if err := proto.Marshal(msg); err != nil { return err }
  2. 85% 成功率 
    If the field truly is optional, edit the .proto to remove `required` and regenerate:
// user.proto
message User { optional string id = 1; }

无效尝试

常见但无效的做法:

  1. 60% 失败

    Produces wire bytes that downstream strict servers reject; the field is still missing.

  2. 75% 失败

    proto2 distinguishes 'unset' from 'zero'; setting zero still counts as set only if you explicitly assign it — but semantically you're sending bad data.
