express-session fails on Node.js 26 #1173
Description
Activity
Something in
supertestclosed the server after the first request. Upgradingsupertestto 7.3.0 fixes this problem - probably forwardemail/supertest@71dc5fb and forwardemail/supertest#891 (this mentions Node.js 26).Simple reproducer (fails on Node.js 26 on Linux with
supertestolder than 7.3.0):const http = require("node:http"); const request = require("supertest"); const server = http.createServer(); server.on("request", (req, res) => res.end("hi")) request(server).get('/').expect(200, (e) => console.error(e)); // null request(server).get('/').expect(200, (e) => console.error(e)); // Error: read ECONNRESET
expressjs/session#1148 has been merged related to this issue. A new release of
express-sessionwould need to follow before there is any change to the outcome of runningcitgm express-session.express-session@1.19.0 is the failing release.
