Redis -> LS -> ES WRONGTYPE Operation against a key holding the wrong kind of value

[dseixas (Daniel Seixas Domínguez)]

Hi,

We're trying to use the combo Redis+LS+ES to try to persist xAPI statements (these statements are JSON strings).

So far, we write correctly in redis, but when LS try to do its thing we get this message:
WRONGTYPE Operation against a key holding the wrong kind of value

A simple example of what we're writing in Redis is:

set xapi '{"id":"jghfj"}' EX 10

My logstash config file is:

input {
  redis {
    host => "127.0.0.1"
    data_type => "list"
    key => "xapi"
   # codec => "json"
    # batch_count => 1
    # threads => 1
  }
}


output {
  elasticsearch {
    hosts => ["localhost:9200"]
    index => "xapi"
  }
  stdout {
        codec => rubydebug
  }
}

We're out of ideas how to get this thing working. Any help is welcome.

BR
Daniel
