Reason for the warning

I have an logstash conf file like

input {
  s3 {
    access_key_id => "redacted"
    secret_access_key => "redacted"
    bucket => "aws-cloudtrail-logs-905418385260-a48e6842"
    delete => false
    interval => 30 # seconds
    prefix => "AWSLogs/905418385260/"
    type => "cloudtrail"
    codec => "cloudtrail"
    # credentials => "/etc/logstash/s3_credentials.ini"
    # sincedb_path => "/opt/logstash_cloudtrail/sincedb"
  }
}

output {
  stdout{
    # codec => "rubydebug"  
  }
  s3 {
    access_key_id => "redacted"
    secret_access_key => "redacted"
    region => "us-east-1"
    bucket => "logstash-test-random"
    prefix => "logs/%{+YYYY.MM.dd}"
    retry_count => 1
    additional_settings => {
      "force_path_style" => true
      "follow_redirects" => false
    }
    time_file => 4
    codec => "json"
    rotation_strategy => "time"    
    temporary_directory => "C:\elk\logstash-8.13.1\config"
  }
}```

whenever i run this conf i get the following warning

Things to note

  1. using codec json , the files are getting uploaded to s3 even though the warning still persists
  2. i have tried to do retry_count = 0 it still showed the warning
  3. logs are getting generated (verified by stdout) and temp file is also getting made

Another issue
using codec cloudtrail in s3 output, i get the same warning about 90 something times and then the program catches some uncaught error and stops( idk why if somebody could tell why would be great)
