Logstash-input-s3 cannot back up with an S3 key that contains characters that need to be URL-encoded

[fukasawah]

Hello.
Regarding the title, Is there any way to fix it?
I suspect it's a bug in the plugin.

• Version: logstash-input-s3-3.5.0
• Operating System: Windows Server 2016
• Config File:

input {
  s3 {
    bucket => "fukasawah-123123"
    access_key_id => "*********"
    secret_access_key => "******"
    region => "ap-northeast-1"
    prefix => "target/"
    backup_to_bucket => "fukasawah-123123"
    backup_add_prefix => "done/"
    delete => true
    interval => 60
    watch_for_new_files => true
  }
}

output {
  stdout { codec => rubydebug }
}

• Sample Data: None
• Steps to Reproduce:
  1. Put "target/あいうえお.csv" to S3 Bucket
  2. run logstash -f this.conf
  • Expect: Copy to #{backup_to_bucket}/#{backup_add_prefix}#{object.key} (eg. fukasawah-123123/done/target/あいうえお.csv)
  • Actual: NoSuchKey Error

AWS SDK Ruby v2 copy_from(:copy_source) must be URL-encoded, but it doesn't look like that's being done in the plugin's process.
