Code Review
This pull request introduces a valuable feature to preserve user-set gRPC status codes when exceptions are raised in Ray Serve deployments. The implementation is well-structured, introducing a gRPCStatusError to carry the context, updating replica methods to wrap exceptions, and modifying the proxy to respect the user's intended status code. The addition of message truncation is a thoughtful improvement to prevent issues with large error messages. The documentation and tests are comprehensive and clearly cover the new functionality.
I've found one potential issue related to handling asyncio.CancelledError on older Python versions, which could lead to inconsistent behavior. My specific comments provide suggestions to address this. Overall, this is a great enhancement to Ray Serve's gRPC capabilities.

ray-project#60482) Fixes ray-project#58851 ### Changes 1. **New `gRPCStatusError` exception class** - Wraps exceptions with user-set gRPC status codes so they flow through Ray's error handling path. 2. **Exception wrapping in replica methods** - `handle_request`, `handle_request_streaming`, and `handle_request_with_rejection` now wrap exceptions with `gRPCStatusError` when the user has set a status code on the gRPC context. 3. **Status code preservation in proxy** - `get_grpc_response_status()` now detects `gRPCStatusError` and returns the user's intended status code instead of `INTERNAL`. 4. **Message truncation** - Added `_truncate_message()` to limit error details to 4KB, avoiding HTTP/2 trailer size limits. 5. **Documentation updates** - Updated the gRPC guide to document the new behavior. --------- Signed-off-by: abrar <abrar@anyscale.com> Signed-off-by: jinbum-kim <jinbum9958@gmail.com>
