Error parsing python, syntax error, unexpected '(' in /etc/syslog-ng/conf.d/kafka.conf

Ubuntu 18.04
Syslog-ng 3.29 installed via pip3

I am using the kafka.conf destination configuration in these instructions: https://syslogng-kafka.readthedocs.io/en/latest/installation.html and getting the following error when running sudo syslog-ng -F:

I have tried cutting and pasting and also entering everything by hand to no avail.

I will try this on 16.04 and see what happens. Thanks @brokenrainbow

With python3 you need to use this format:

destination syslog_to_kafka {
  python(
    class("syslogng_kafka.kafkadriver.KafkaDestination")
      on-error("fallback-to-string")
      options(
        "hosts" "localhost:9092,localhost:9093"
        "topic" "security-eset"
      )
  );
};
