Hi  
can you please help what i am doing wrong.. this same config works fine with ver 12

input {

jdbc {

```
statement_filepath => "/usr/share/logstash/pipelines/sql/database_query.sql"
#important the driver library must be included in the appropriate path (via docker compose)
jdbc_validate_connection => true
jdbc_connection_string => "jdbc:oracle:thin:@database.something:2222/DBASE"
jdbc_driver_class => "Java::oracle.jdbc.driver.OracleDriver"
jdbc_driver_library =>"/usr/share/logstash/logstash-core/lib/jars/ojdbc8.jar"
jdbc_user => "xxxxxxxxx"
jdbc_password => "xxxxxxxxx"
schedule => "* * * * *"
jdbc_page_size=> "1000"
    jdbc_paging_enabled => "true"
last_run_metadata_path => "/usr/share/logstash/data/database_query"

```

what i get is this error:

[2022-02-22T13:23:00,453][ERROR][logstash.inputs.jdbc][xxx\_jdbc][5bab07f84e16e29e6022f3ba3bd190c8ab35e6ea0e5127a123cbea4c5ce79c5e] Unable to connect to database.
