@ypliypli can you please provide more of your code? It will help if you create a minimum repo which repoduces this error i.e. only koa and koa-session and some of your code. It will be event better if you can write a test.

I've used your code and added minimal code to init koa. There are no errors in my setup.

package.json:

  "dependencies": {
    "koa": "^2.6.2",
    "koa-session": "^5.10.0"
  },

app.js

const Koa = require('koa');
const app = new Koa();

const session = require('koa-session');

app.use(session({
    key: 'koa:sess', /** (string) cookie key (default is koa:sess) */
    /** (number || 'session') maxAge in ms (default is 1 days) */
    /** 'session' will result in a cookie that expires when session/browser is closed */
    /** Warning: If a session cookie is stolen, this cookie will never expire */
    maxAge: 86400000,
    overwrite: true, /** (boolean) can overwrite or not (default true) */
    httpOnly: true, /** (boolean) httpOnly or not (default true) */
    signed: true, /** (boolean) signed or not (default true) */
    rolling: false, /** (boolean) Force a session identifier cookie to be set on every response. The expiration is reset to the original maxAge, resetting the expiration countdown. (default is false) */
    renew: false, /** (boolean) renew session when session is nearly expired, so we can always keep user logged in. (default is false)*/
  }, app));

app.listen(3000, () => console.log('Listening on port ' + 300));

is this issue solved? I met the same problem. And I am sure it has nothing to do with the version of koa and koa-session, as it works in my demo with the same version.
