Root Cause

A proto2 message with required fields was not fully populated before serialization. In proto3, required fields are not supported, but if using proto2, this error occurs.

generic

中文

proto2 消息中的必填字段在序列化前未完全填充。在 proto3 中不支持必填字段，但如果使用 proto2，则会出现此错误。

Workarounds

  1. 95% success 
    msg := &YourMessage{
    Name: proto.String("value"), // Required field
}
if err := proto.Marshal(msg); err != nil {
    log.Fatalf("marshal failed: %v", err)
}
  2. 90% success 
    // Update .proto file to syntax = "proto3";
// Remove required keyword; regenerate code

Dead Ends

Common approaches that don't work:

  1. 100% fail

    Serialization will still fail or produce invalid data that cannot be parsed later.

  2. 70% fail

    An empty string is still a value, but if the field is required, it must be explicitly set; an empty string may be considered unset in some implementations.
