Root Cause

The server returned a malformed or corrupted protobuf message that the client cannot parse.

服务器返回了格式错误或损坏的 protobuf 消息，客户端无法解析。

Workarounds

  1. 85% success Ensure client and server use the same protobuf version and the same .proto file. Recompile both sides. Example: protoc --python_out=. myproto.proto on both client and server.

  3. Validate the server's response payload using a protobuf validator or schema registry to catch mismatches early.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The malformed response is generated by the server; client restart doesn't fix server-side serialization issues.

  2. 70% fail

    The issue is often due to incompatible protobuf versions between client and server; both must be aligned.

  3. 80% fail

    If the server consistently sends malformed data, ignoring the error will cause repeated failures.
