Root Cause

The client sent a request with invalid or missing required fields, often due to missing validation.

generic

中文

客户端发送的请求包含无效或缺少必填字段，通常是由于缺少验证。

Workarounds

  1. 90% success Validate all required fields before making the RPC call. 
    if req.Name == "" {
    return fmt.Errorf("name is required")
}
if req.Age < 0 {
    return fmt.Errorf("age must be non-negative")
}
resp, err := client.SomeRPC(ctx, req)
  2. 85% success Use protobuf validation annotations and generate validation code. 
    In .proto: message MyRequest { string name = 1 [(validate.rules).string.min_len = 1]; }
Then call: if err := req.Validate(); err != nil { return err }

Dead Ends

Common approaches that don't work:

  1. Send the request with empty fields again. 100% fail

    The server will reject it for the same reason.

  2. Ignore the error and proceed with partial data. 95% fail

    The RPC failed, so no data was processed.
