Fluentd sending warn logs to elasticsearch which shouldn't be sent as per config

[SoodPrerit]

I am facing an issue where fluentd floods a lot of logs when elasticsearch memory utilization is more. Below are the log lines which shouldn't be pushed to elasticsearch but are getting pushed and in millions

[warn]: [elasticsearch] failed to flush the buffer. retry_times=125 next_retry_time=2023-09-05 12:29:07 +0000 chunk="604972dd0d1868f9a5a037f5bbe60c81" error_class=Fluent::Plugin::ElasticsearchOutput::RecoverableRequestFailure error="could not push logs to Elasticsearch cluster ({:host=>"vpc-XXXXXXXXXXXXXXXXXXXXXXXX.eu-XXXXX.es.amazonaws.com", :port=>443, :scheme=>"https", :user=>"xxxxxxxx", :password=>"XXXXXX"}): request timed out"

In my fluentd config I have already excluded the logs for fluentd to be sent to elastcisearch using below config

    <label @FLUENT_LOG> 
      <match fluent.**> 
        @type null 
        @id ignore_fluent_logs 
      </match> 
    </label>

I am not sure why even after with above config, fluentd is sending these log lines to the elasticsearch index ??? Please help answering this question.
