hono/body-limit middleware fails to return response if file is too large.

[hanool]

description

When using hono/body-limit middleware with @hono/node-server, large requests that exceed the body limit receive ERR_CONNECTION_RESET instead of error response.

environment

• hono": "^4.12.8"
• @hono/node-server": "^1.19.11"
• node: 24.13.0

reproduce

1. Create hono project with quick-start
2. Add body-limit as usage example
3. Post request to /upload with body size much larger than 50kb

or I have created reproduce repo

Note: This does not occur with small payloads slightly over the limit (e.g. 51KB). It reliably occurs with larger payloads (e.g. 1MB+). I believe this is because the client is still actively sending the request body when the server responds and closes the connection — smaller payloads finish transmitting before the socket is destroyed.
