Redis Session Storage Fails After Cursor Refactor
User sessions are no longer persisting to Redis after Cursor reorganized your session middleware code. Users are logged out on page refresh, defeating the purpose of persistent sessions.
The Redis client may be misconfigured or the session store initialization was altered during the refactoring.
Error Messages You Might See
Error: connect ECONNREFUSED 127.0.0.1:6379
RedisStore requires a redis client
Session undefined
Failed to serialize session
Common Causes
- Redis connection not established before session middleware initialization
- Session store options (ttl, prefix) changed without updating retrieval logic
- RedisStore instantiation missing or using wrong Redis client instance
- Session data serialization changed, making old sessions unreadable
- Redis key prefix changed, causing session lookups to fail
How to Fix It
Ensure Redis client connects before app.use(sessionMiddleware). Verify RedisStore configuration matches retrieval: new RedisStore({client: redisClient, prefix: 'sess:'}). Check Redis CLI for stored keys: redis-cli KEYS 'sess:*'

Jacek Rozanski
Senior PHP/Symfony developer and DevOps engineer with 20+ years of professional experience, running opcode.pl (web development agency, est. 2004).
Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month.
What I bring to AI-built apps:
- I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0
- I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture)
- I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting
- I integrate external services: payment providers, email systems, partner APIs, SSO/auth
Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code.
Based in Poland (CET timezone). Available for async work and calls during EU/US business hours.

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

How do I check if sessions are in Redis?
Use redis-cli KEYS 'sess:*' to list sessions. Use redis-cli GET 'sess:sessionid' to view session data.
Why are sessions not surviving restart?
Verify Redis is persisting to disk (RDB or AOF). Check redis.conf configuration.
