I had a Kamailio 5.6.4 server using the DB_REDIS module for quite some time without a password on the Redis DB working just fine.

A few days ago I decided to add a password to Redis and modify the Kamailio config file with the following line per the documentation to be able to authenticate:

modparam("db_redis", "db_pass", "r3d1sPass")

Since that moment, I see the following errors in the Kamailio logs:

......

kamailio: ERROR: <core> [core/modparam.c:175]: set_mod_param_regex(): parameter <db_pass> of type <1:string> not found in module <db_redis>
kamailio: CRITICAL: <core> [core/cfg.y:3790]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 556, column 49: Can't set module parameter

......

The documentation I am reading is here:

https://www.kamailio.org/docs/modules/devel/modules/db_redis.html#db_redis.p.db_pass

Could someone help me figure out what I am doing wrong?

Many thanks,

Nick
