Unable to get Postgres for Logstash input

[Isra]

I am using the following:
Logstash 5.5.1
postgresql-42.1.4.jar
Java version 1.8.0_141
Windows 10

The following is my logstash config file

input {
        jdbc {
                jdbc_driver_library     => "PATH\TO\postgresql-42.1.4.jar"
                jdbc_driver_class       => "org.postgresql.Driver"
                jdbc_connection_string  => "jdbc:postgresql://THESERVER:PORT/user=isra"
                jdbc_user               => "isra"
                jdbc_password           => "123conn"
                statement               => "SELECT * from table1"
        }
}

output {
        stdout { codec => json_lines }
}

Yet I am getting the following error when attempting to run logstash. Any idea why?
