[fluent-plugin-s3 / s3 / MinIO / timekey] Force to create single log file on MinIO when timekey condition has been met

[arepusb]

Hello there!
I use fluent-plugin-s3 and according my configuration it should send logs from few files to MinIO once per day.
Hers is the configuration:

<match projectname>
    @type s3
    aws_key_id "#{ENV['MINIO_ROOT_USER']}"
    aws_sec_key  "#{ENV['MINIO_ROOT_PASSWORD']}"
    s3_bucket tenants
    format json
    force_path_style true
    s3_endpoint "http://#{ENV['MINIO_HOST']}:#{ENV['MINIO_PORT']}/"
    path "#{ENV['TENANT_ID']}/logs/projectname-"     # This prefix is added to each file
    time_slice_format %Y%m%d%H%M  # This timestamp is added to each file name
    #s3_object_key_format %{path}%{time_slice}.%{file_extension} # Should be commented because target log file will be overwritten few times and logs wil be lost. 

    <buffer tag,time>
        @type file
        path /fluentd/logs/
        timekey 1440m  
        timekey_wait 10m
        flush_mode lazy
        timekey_use_utc true
        chunk_limit_size 256m
    </buffer>
</match>

I noticed that fluent-plugin-s3 often creates on MinIO more than one file per day.

Example,
projectname-202401240532_3.gz
projectname-202401240532_2.gz
projectname-202401240532_1.gz
projectname-202401240532_0.gz

I would like to have single log file on MinIO per day.
To achieve this goal I tried to play with s3_object_key_format property.
default value = %{path}%{time_slice}_%{index}.%{file_extension}
I changed it to %{path}%{time_slice}.%{file_extension}. As result I lost part of the logs. Looks like target log file was overwritten few times and I saw only data from the latest iteration.

How to force fluent-plugin-s3 to create only single file on MinIO when timekey condition has been met (and not lose data)?
