Problem with mk_redis with password since 2.2.0p21

CMK version: 2.2.0p21
OS version: Debian 12

Hello,

Since checkmk 2.2.0p21 plugin mk_redis for hosts with redis instances that require a password does not work anymore.

It seems to be related to the newly introduced REDISCLI_AUTH env variable used.

When debugging by executing the plugin code, I get the following output

root@myhost:/usr/lib/check_mk_agent/plugins/3600# export MK_CONFDIR=/etc/check_mk
root@myhost:/usr/lib/check_mk_agent/plugins/3600# ./mk_redis 
<<<redis_info:sep(58)>>>
[[[Local|127.0.0.1|6379]]]
REDISCLI_AUTH=mypasswordhere: No such file or directory

related config file :

root@myhost:~# cat /etc/check_mk/mk_redis.cfg 
#!/bin/sh
REDIS_INSTANCES=(Local)
REDIS_HOST_Local="127.0.0.1"
REDIS_PORT_Local="6379"
REDIS_PASSWORD_Local='mypasswordhere'

replacing

waitmax 3 ${REDIS_CLI_COMMAND} "${REDIS_ARGS[@]}" || true

by

export REDISCLI_AUTH=${!PASSWORD}
waitmax 3 redis-cli "${REDIS_ARGS[@]}" || true

in the mk_redis plugin code works…

Anyone observe the same behavior since 2.2.0p21 ?

Thanks
