## Bug Report

### Version
tonic = "0.12.2"
prost = "0.13.2"
[build-dependencies]
tonic-build = "0.12.2"

### Platform
arm macOS
istio envirment in docker desktop

### Description

i using an Istio WebAssembly (WASM) plugin with the proxy-wasm-rust-sdk. In this plugin,i sending a gRPC request to a Tonic-implemented server without a sidecar. Through packet capture, i observed that the server receives the message but doesn't process it. When i replaced the Tonic server with a Go-implemented gRPC server, the requests were processed normally.
