根因分析

通过gRPC接收的protobuf消息包含一个具有意外线类型的字段，通常是由于客户端和服务器之间的模式不匹配。

English

The protobuf message received over gRPC has a field with an unexpected wire type, often due to schema mismatch between client and server.

generic

解决方案

  1. 95% 成功率 Regenerate Go protobuf code from the same .proto file on both sides. 
    protoc --go_out=. --go-grpc_out=. *.proto
  2. 80% 成功率 Use protojson format for debugging to identify field type mismatches. 
    import "google.golang.org/protobuf/encoding/protojson"
b, _ := protojson.Marshal(msg)
log.Printf("%s", b)

无效尝试

常见但无效的做法:

  1. Restart both client and server without checking proto files. 90% 失败

    The issue is structural mismatch, not transient state.

  2. Update only the client binary without regenerating proto code. 85% 失败

    Stale generated code still has old field definitions.
