Hey,  
I'm trying to upload data from logstash to s3. I couldnt find any way to use a dynamic bucket name. In my json input I'm getting a key that is called bucket\_name and I would like to use that as the destination bucket in s3.

I saw [this issue](https://github.com/logstash-plugins/logstash-output-s3/issues/168) that was opened 2 years ago and I wanted to know if there is some kind of solution to it..

```
My output :  
output {
  s3 {
    bucket => "%{bucket_name}"
    codec => "line"
    prefix => "%{+YYYY.MM.dd}}"
    temporary_directory => "/etc/logstash/s3"
  }
}

```

If I try to add the bucket\_name variable into the prefix and use a hard\_coded bucket\_name everything works...  
When the bucket\_name is dynamic I'm getting the following error :  
` Error validating bucket write permissions! {:message=>"The specified bucket is not valid.", :class=>"Aws::S3::Errors::InvalidBucketName",`
