Unable to configure plugins: (ArgumentError) Cannot determine timezone from nil - Logstash

Question

I am trying to move data from my Oracle database to Elasticserach via Logstash. I get this timezone error whenever i try to run logstash. bin/logstash -f D:\\ElasticSearch\\logstash-8.10.2\\config\\oracle-config.conf Error:

[2023-10-23T09:13:35,247][ERROR][logstash.agent           ] Failed to execute action {:action=>LogStash::PipelineAction::Create/pipeline_id:main, :exception=>"Java::JavaLang::IllegalStateException", :message=>"Unable to configure plugins: (ArgumentError) Cannot determine

This is my logstash config

input {
  jdbc {
    jdbc_connection_string => "jdbc:oracle:thin:@//[my_ip]/[my_service]"
    jdbc_default_timezone => "Asia/Jakarta" //my timezone: UTC:+7
    jdbc_user => "[my_user]"
    jdbc_password => "******"
    jdbc_driver_library => "C:/Users/kynk/Downloads/jdbc/lib/ojdbc8.jar"
    jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
    statement => "SELECT *
                  from mb_config_cross_sell;"
  }
}
output {
    stdout{
    codec => rubydebug
    }
}

I also try to search and try those thread thread_1 thread_2 and more... but the result is the same (Cannot determine timezone from nil) Anyone can shred some light? Many thanks.
