express redis session-management javascript

Could someone explain I'm experiencing issues with user session management in my Express application using `express-session` and `connect-redis` for storing sessions in Redis. The question arises when multiple users log in simultaneously; their sessions seem to overwrite each other, leading to unexpected behavior. For example, user A logs in and their session is stored correctly, but then user B logs in and somehow user A's session data is retrieved instead. Here's my basic setup: ```javascript const session = require('express-session'); const RedisStore = require('connect-redis')(session); const redisClient = require('redis').createClient(); app.use(session({ store: new RedisStore({ client: redisClient }), secret: 'mySecret', resave: false, saveUninitialized: false, cookie: { secure: false } })); ``` I've confirmed that Redis is running and accessible, and I'm using the latest versions of the relevant packages: - express: 4.18.1 - express-session: 1.17.2 - connect-redis: 6.0.0 I also made sure to set unique session IDs by calling `req.sessionID`, but the scenario continues. I’ve tried logging the `req.session` object for both users during the login process to see if they are actually being assigned different session IDs, and they are. However, when I check Redis, it seems like the session keys are getting mixed up. Each time a user logs in, it appears as though the previous session data is being overwritten. I’ve also ensured that the Redis store is correctly configured and that I'm using a unique `sessionId` generation method. Is there a specific configuration I might be missing, or is there a known scenario with these versions of the packages? Any help would be greatly appreciated! Is there a better approach?
