Logstash errors while executing ruby code (Ruby exception occurred: allocator undefined for Float)

Was trying to execute below code in logstash but it keeps throwing an exception.

if [received_at] and [sent_at] {
    ruby {
      init => "require 'time'"
      code => "
        received_by_finacle = (Time.parse(event.get('received_at').to_f)*1000).round(2);
        sent_out_by_finacle = (Time.parse(event.get('sent_at').to_f)*1000).round(2);
        event.set('delta', (sent_out_by_finacle - received_by_finacle)).to_s;
        event.set('epoch_received_at_in_milliseconds', received_by_finacle);
        event.set('epoch_sent_at_in_milliseconds', sent_out_by_finacle);
        "
      add_tag => [ "calculated_time_difference" ]
    }
}

the error returned is 

[2018-10-10T22:01:05,631][ERROR][logstash.filters.ruby ] Ruby exception occurred: allocator undefined for Float
[2018-10-10T22:01:05,640][ERROR][logstash.filters.ruby ] Ruby exception occurred: allocator undefined for Float

any ideas why please?

Thanks to a logstash community member @Ganesh_Venkataraman, i was able to figure the solution out. I had to add a "rescue nil" (will read up more on that later). Here's the code that finally worked for me. 

if [received_at] and [sent_at] {
    ruby {
        init => "require 'time'"
        code => "
            received_by_finacle   = (Time.parse(event.get('received_at')).to_f)*1000;
            sent_out_by_finacle   = (Time.parse(event.get('sent_at')).to_f)*1000;
            timetaken = (sent_out_by_finacle - received_by_finacle) rescue nil;
            event.set('time_delta',timetaken);
            event.set('epoch_received_at_in_milliseconds',received_by_finacle);
            event.set('epoch_sent_at_in_milliseconds',sent_out_by_finacle);
            "
            add_tag => [ "calculated_time_difference" ]
    }
}

Thanks.
