Logstash com.mysql.jdbc.Driver error

Elastic Stack Logstash

Hi. I have logstash 7.4.2 , mysql 5.7 , This is my config:

filter {
  jdbc_static {
    loaders => [ 
      {
        id => "products-table"
        query => "select id,name from products;"
        local_table => "products"
       }
    ]
    local_db_objects => [
      {
        name => "products"
        index_columns => ["id"]
        columns => [
          ["id", "int(11)"],
          ["name", "varchar(100)"]
        ]
      }
    ]
    local_lookups => [ 
      {
        id => "get-product-name"
        query => "SELECT name FROM products WHERE id = :pid"
        parameters => { pid => "[product]" }
        target => "product_name"
      }
    ]
    jdbc_driver_library => "mysql-connector-java-5.1.48-bin.jar"
    loader_schedule => "* */1 * * *"
    jdbc_user => "user"
    jdbc_password => "pass"
    jdbc_driver_class => "com.mysql.jdbc.Driver"
    jdbc_connection_string => "jdbc:mysql://IP:3306/dbname"
  }
}

The jar file is in the directory and I've installed plugin with logstash-plugin install logstash-input-jdbc.
I get this error:

What should I do ? Thanx

Try to use the full absolute path to the .jar file for jdbc_driver_library.
