Plug.Parsers was trying to parse protobuf bodies as JSON, failing with 400 errors before the request reached the controller. Changes: - Added custom BodyReader to endpoint that skips parsing for protobuf - When Content-Type is application/x-protobuf, return empty body to parser - Controller reads the raw body directly for protobuf requests - Added error handling for protobuf decode failures in heartbeat endpoint This fixes the 400 errors agents were seeing on heartbeat requests.
