具有必填字段（proto2语法）的protobuf消息在反序列化时缺少必填字段。

A protobuf message with required fields (proto2 syntax) is missing a required field during unmarshaling.

generic

90% 成功率 Migrate from proto2 to proto3 where all fields are optional.
```
syntax = "proto3";
message UserRequest { string user_id = 1; }
```
85% 成功率 Ensure sender populates all required fields before sending.
```
if msg.UserId == nil { return errors.New("user_id required") }
```

常见但无效的做法:

Make the field optional in proto2 without changing schema. 90% 失败
Required is a proto2 concept; cannot be removed without schema change.
Set a default value for the field. 95% 失败
Required fields must be explicitly set by sender.
