根因分析

服务器发送的 gRPC 响应缺少必需的 `grpc-status-details-bin` 尾部，客户端期望该尾部以进行更丰富的错误处理。

English

The server sent a gRPC response without the required `grpc-status-details-bin` trailer, which is expected by the client for richer error handling.

解决方案

  1. Ensure the server sets the `grpc-status-details-bin` trailer using the `google.rpc.Status` proto. Example in Go: `st := status.New(codes.Internal, "error").WithDetails(&errdetails.RetryInfo{RetryDelay: &duration.Duration{Seconds: 1}})` then `st.Err()`.
  2. On the client, fall back to parsing `grpc-status` and `grpc-message` trailers if details are missing.

无效尝试

常见但无效的做法:

  1. 60% 失败

    Retries are unrelated to status details in trailers.

  2. 80% 失败

    Status details are only in trailers; headers may not contain the full error info.

  3. 40% 失败

    The issue is not version-specific; it's about whether the server populates the trailer.
