Cache handler is not configured yet

[cbou]

Brief Description of the Bug In my NextJS I can't manage to make the shared cache working even thought I follow the installation instructions... So I try to start from the example project and also get trouble connecting to my Redis instance.

Severity Major

Frequency of Occurrence Always

Steps to Reproduce

1. Create example project: npx create-next-app --example cache-handler-redis cache-handler-redis-app
2. Create dockerfile with redis:

services:
    redis:
        image: 'redis/redis-stack:latest'
        container_name: 'my-redis'
        ports:
            - '6379:6379'
        volumes:
            - redis-data:/data

volumes:
    redis-data:

3. Start Redis docker-compose up
4. Check connection to redis redis-cli Should output 127.0.0.1:6379>
5. Start building project with NEXT_PRIVATE_DEBUG_CACHE=1 npm run build

Expected vs. Actual Behavior I would expect the cache to be saved in Redis. Instead it's saved in the local-lru as the log shows.
