MQTT Sensor for plexpy/tautilli setup problem

I setup mqtt and can listen to the topic from the Hassbian Pi but adding these sensors I am getting an unknown status. I am not sure what I am doing wrong? Any help would be greatly appreciated. Sorry if this is an easy question. Still trying to learn.

# Plex
  - platform: mqtt
    name: plex_status
    state_topic: plexpy/status 
    value_template: '{{ value_json.body }}'
  - platform: mqtt
    name: plex_type
    state_topic: plexpy/type
    value_template: '{{ value_json.body }}'
  - platform: mqtt
    name: plex_player
    state_topic: plexpy/player
    value_template: '{{ value_json.body }}'

Can you paste the output of this. It is impossible to check your configuration if nobody can see the messages that are being sent.
