Hello I am using logstash 5.6.9. I am simply trying to read from my local redis server and print it to console using logstash, here is my configuration 
input {
redis {
host => 'localhost'
data_type => 'list'
key => 'tutorials'
type => 'redis-input'
}
}
output {stdout { codec => rubydebug } }
Still I am facing _jsonparsefailure .
I am inserting data to my redis server using the following command.
LPUSH tutorials aaa
LPUSH tutorials aa
LPUSH tutorials a
Here is a snapshot of my error what I am doing wrong here.
Basically I want to get all the values under the key and check if a particular value exists.
Thank you
