Problem with session storage in redis store?

Question

JavaScript

I store sessions like this:

var session = require('express-session'),
redisStore = require('connect-redis')(session),
sessionStore = new redisStore();

app.use(session({key: 'express.sid', store: sessionStore, secret: 'secret', resave: true, saveUninitialized: true }));

However, recently, I stopped recording sessions in redis, because when I call sessionStore.get(sessionID, function(err, session) {} I get an undefined response.
To check, I put the project on another server, the problem disappeared.
My assumptions are - redis just ran out of space to store new sessions, or old session records just won't be deleted.What
could be the problem and how can I fix it?

Answer 1

How many times do I think that the problem is in one thing, but in fact it turns out to be completely different.
It's decided, everything is fine with radish in this regard.
