Command line sensor - port check

Configuration
1

Hi, I have several binary sensors setup to check port is open, this works when the port is accessible but when the port is closed I’m getting error in logs instead of the updating the binary sensor.

Where am i going wrong? :rofl:

  - binary_sensor:
      name: NAS Port
      device_class: connectivity
      unique_id: NASPORT
      command: 'nc -z 192.168.5.100 1919 > /dev/null 2>&1 && echo success || echo fail'
      payload_on: "success"
      payload_off: "fail"
      icon: >
          {% if value == "fail" %} mdi:lan-disconnect
          {% else %} mdi:transit-connection-variant
          {% endif %}
      scan_interval: 120
