Parrot Flower Power json parse

I have a very long json from https://api-flower-power-pot.parrot.com/garden/v1/status
I’m getting this response and saving to a file. I’m trying to setup few sensors from this fine but the parsing is failing all time.
[homeassistant.helpers.template] Error parsing value: ‘value_json’ is undefined (value: }, template: {{ (value_json.locations[0].fertilizer.gauge_values.current_value) }})
I checked the json value extraction online and it’s ok with locations[0].fertilizer.gauge_values.current_value

Can anybody help me to get moisture and fertiliser values? Thanks.
