Root Cause

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

Workarounds

  1. 85% success 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()`. 
    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. 75% success On the client, fall back to parsing `grpc-status` and `grpc-message` trailers if details are missing.

Dead Ends

Common approaches that don't work:

  1. 60% fail

    Retries are unrelated to status details in trailers.

  2. 80% fail

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

  3. 40% fail

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