I have an logstash conf file like ````auto input { s3 { access_key_id => "redacted" secret_access_key => "redacted" bucket => "aws-cloudtrail-logs-905418385260-a48e6842" delete => false interval => 30

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 ```` [2024-06-04T11:45:59,223][WARN][logstash.outputs.s3][main] Uploading failed, retrying (#674 of

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)
