Root Cause

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

generic

中文

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。

Workarounds

  1. 95% success 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% success 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 }

Dead Ends

Common approaches that don't work:

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

    The message is still invalid; error will repeat.

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

    May cause data corruption or further validation errors.
