I am pulling a JSON input via http\_poller, the data has "\n" throughout the data that I would like to remove it

Here is an example of a date that contains the "\n"

"O 151007Z FEB 17\n"

Here is my input

input{  
http\_poller{  
urls =\> {  
test1 =\> "..."  
test2 =\> {  
method =\> get  
url =\> "..."  
headers =\> {  
Accept =\> "application/json"  
}  
}  
}  
codec =\> "json"  
}  
}

I have tried  
filter{  
mutate { gsub =\> ["message", "[\n]", "" ] }  
}

and suggestions from here with no success.

```
Do not escape the newline.

mutate { gsub => [ "message", "
", "" ] }
```

</div>

My new input is

```
input {
 http_poller {
    urls => {
      test1 => ".."
      test2 => {
        method => get
        url => "..."
        headers => {
        Accept => "application/json"
        }
     }
    }
    type => "..."
    request_timeout => 60
    codec => "json"
    metadata_target => "http_poller_metadata"
  }
}
filter {
   json {
     source => "message"
   }
   mutate { gsub => [ "messages", "
 ", "" ] }
}

```

The output has not changed and is

`"O 151007Z FEB 17\n"`

In Kibana, the "\n" is only visible in the JSON source, but it causes issues when trying to parse the date as I am only able to parse dates without the new line \n "O 151007Z FEB 17" correctly.
