Driver 'redis' failed - Fallback to 'useAutoDriver()'

[ne20002]

I have a list of errors when trying to use redis with my installation.

RedisException: ERR AUTH <password> called without any password configured for the default user. Are you sure your configuration is correct? in /var/www/html/src/Core/Cache/Type/RedisCache.php:68

I use podman to create a pod including the redis container (I do the same with Nectcloud).

Can you output if there's a config value in the db:

SELECT * FROM config WHERE k='redis_password';

or as environment variable

printenv | grep REDIS_

It seems like there's a non-null variable, but it's set to empty .. I'll add a fix for it at the upstream, but maybe we can find the root-cause for it

[ne20002]

Here ya go:

 env | grep REDIS
 REDIS_PORT=6379
 REDIS_HOST=friendica-friendica-redis

With latest image (stable-fpm) the substitution error in entrypoint.sh (as in #196) is gone, but no change to redis passwort error. I removed both env entries to get Friendica running without the error in the protocoll.

[ne20002]

I now applied the changes from friendica/friendica#11250 manually. Friendica starts with stating using Redis as session handler, no more errors shown in protocoll.

Can I close this issue because you found a workaround until the root-cause is fixed?
