Is this a bug report?

POST requests with form data seems to be timedout at 60 seconds. Happens in node version 13.x and 14.x but not 12.x. This might be a bug in node-http-proxy.

Steps to reproduce

1. Create script testUpload.sh (or use scripts/testUpload.sh in supplied repo)

ENDPOINT=$1 FILE=large.file RATELIMIT=10M echo "Testing upload to $ENDPOINT" if ! [ -f "$FILE" ]; then echo "Generating test file..." dd if=/dev/zero of=$FILE bs=1048576 count=2048 fi echo "Testing upload at $RATELIMIT" curl -X POST $ENDPOINT -H "accept: application/json" -H "Content-Type: multipart/form-data" -F "file=@${FILE}" --limit-rate $RATELIMIT --progress-bar --verbose -o ${RATELIMIT}.out

2. Run script as testUpload.sh URL
3. Wait for it

After 60 seconds I recieve

... * Recv failure: Connection reset by peer * stopped the pause stream! * Closing connection 0 

Simiar behavior is seen in browser.The request gets net::ERR_CONNECTION_RESET with error message TypeError: Failed to fetch in Chrome and TypeError: NetworkError when attempting to fetch resource. in Firefox.

Expected behavior

Request goes on until finished.

Actual behavior

Request vanishes. Our server got yielded client disconnected. Client never receives a response.

Setup

Frontend is created with Create-React-App with a separate API on port 5000. setupProxy.js is configured as

const { createProxyMiddleware } = require("http-proxy-middleware"); const TIMEOUT = 30*60*1000; module.exports = (app) => { app.use( "/api", createProxyMiddleware({ target: "http://127.0.0.1:5000", changeOrigin: true, pathRewrite: { "^/api": "", }, proxyTimeout: TIMEOUT, timeout: TIMEOUT, onError: (err, req, res) => console.log(err) }) ); };

client info

The app is run inside Docker container based on node:14.5.0-alpine. Same error is encountered when run an Ubuntu system. This is the case for node versions 13.x and 14.x but not 12.x.

target server info

A Python FastAPI server that allows file uploads on endpoint POST /v1/storage.
