Hi guys! I am trying to index log in json format:

> `{"interests": "dota", "car": null, "surname": "Zhussipnazar", "name": "Daulet", "age": 20}`

But it gives me error, `_jsonparsefailure` , because logstash cant handle value 'null'  
How can I handle null value in json?

my config

> file {  
> path =\> "/var/log/test.log"  
> sincedb\_path =\> "/dev/null"  
> codec =\> "json"  
> }  
> filter {  
> json {  
> source =\> "message"  
> }  
> }  
> output {  
> stdout {  
> codec =\> rubydebug  
> }  
> }

Is the null value really what trips up Logstash? What's the exact error message (use copy/paste)?
