Hi, I am new to logstash. How can I read values which are saved in redis-server under the key ":1:logstash"? if the type of ":1:logstash" is string.. I have an input setting like this:

redis {  
host =\> "some\_redis\_server"  
key =\> ":1:logstash"  
data\_type =\> "list"  
codec =\> json  
type =\> "redis"  
tags =\> ["redis"]  
}

and when I run logstash it gives me an error: [logstash.inputs.redis] Redis connection problem {:exception=\>#\<Redis::CommandError: ERR Error running script (call to some\_value): @user\_script:2: WRONGTYPE Operation against a key holding the wrong kind of value\>}
