S3 plugin - unable to change file extension of data in bucket


I'm currently using the s3 plugin to upload logs from logstash into an s3 bucket. I'd like the uploaded files to be of the type json with a file extension of .json

My problem is that the uploaded files keep appearing as .txt text files even though I have made numerous changes to the s3 plugin code. The format of the file content is json but it has a file extension of .txt

Has anyone else experienced this issue? I don't know if it is because logstash runs constantly and locks the file while building it?

I would really appreciate some assistance.


I didn't find any answers regard this issue, please someone help!
