Hi, I need to store my logstash output to s3 as json file. But upon checking the output files in s3, it is stored as .txt format.

Here is my output code:

```
output {
      s3 {
           region => "${elkRegion}"
           bucket => "${s3Bucket}"
           size_file => 2048
           time_file => 5
           codec => "json"
           prefix => "output/%{+YYYY}/%{+MM}/%{+dd}"
         }
}

```

Here is the sample file generated on s3:

```
ls.s3.0673d29c-4f0f-4c32-8f3c-fc066374add7.2020-07-24T02.55.part6.txt

```

I also tried using json\_lines and removing double quotes but still not working. Please let me know what I am missing. Thanks
