Conditional filtering not working in logstash

Elastic Stack Logstash

I think the conditional is wrong, the fields are not in the shape that you are expecting.

That is why I asked you to post output from stdout.
e.g. Something like:

{
     "log_event" => {
             "id" => "rtwert",
           "bank" => "yes",
           "proc" => nil,
          "count" => "5",
        "session" => "****",
    },
      "@version" => "1",
          "host" => "Elastics-MacBook-Pro.local",
       "message" => "blah bla blah",
      "sequence" => 0,
    "@timestamp" => 2019-02-05T11:31:45.347Z
}
