Redis ClientClosedError after cookie is set

[Alphacode18]

I am currently implementing sessions with Redis. I have followed along and have spent sometime debugging on my own, but I can't seem to solve this error.

I am able to send a request, a cookie is set but the server promptly crashes after that with this promise rejection. Any ideas as to what may be going wrong?

I happen to have this same error and wondering if you solved this or not?

[Alphacode18]

@han109k No, I'm still waiting on a reply! Though I'm thinking of using the ioredis package to see if it makes a difference.

@benawad is busy with Voidpet it seems 😅

[han109k]

I think I got solved the problem for now at least. You just need to change the redis configuration part:

import { createClient } from 'redis';
const redisClient = createClient({ legacyMode: true });
await redisClient.connect();

connect-redis's new version causes an issue I guess

[Alphacode18]

@han109k Yes, this fixes it! Agreed, connect-redis' version difference seems to be the issue. Thanks a lot!
