根因分析

客户端发送的protobuf消息中必填字段为空或无效，违反了服务器端验证规则。

English

The client sent a protobuf message with a required field left empty or invalid, violating server-side validation rules.

generic

解决方案

  1. 95% 成功率 Validate all required fields before sending the RPC. 
    if req.Name == "" { return errors.New("name must not be empty") }
resp, err := client.CreateUser(ctx, req)
  2. 90% 成功率 Use protovalidate library to enforce constraints client-side. 
    import "github.com/bufbuild/protovalidate-go"
validator, _ := protovalidate.New()
if err := validator.Validate(req); err != nil { return err }

无效尝试

常见但无效的做法:

  1. Ignoring the error and resending the same message. 100% 失败

    The message is still invalid; error will repeat.

  2. Setting the field to a random non-empty string without understanding the requirement. 80% 失败

    May cause data corruption or further validation errors.
