@User , you can solve this by changing

req.session.userId

to

req.session.getUserId()

. The

userId

field exists, but it's

private

. This is an error in the example we have, will fix it. Then: -

(req.session as any).getUserId()

- or by

import {SessionContainer} from "supertokens-node/recipe/session"
let session: SessionContainer = req.session
let userId = session.getUserId()
