Local json parse via command_line sensor and jq not returning all data

Configuration
1

Hello there,
could anybody help me see what I’m missing in my solution? I have a json file stored the custom_components folder. What I want is to parse all 24 values to 24 unique entities/attributes, so I can make a plot over them.
I’m trying to use command_line sensor with jq function. I was even able to get 1 of the values, but not all of them.
The jq output looks like this:

`$ jq '.z' output.json
{
  "0": 0.6192634,
  "1": 1.1251751,
  "2": 0.5181792,
...
}`

while the config is like:

- platform: command_line
  name: nrg
  command: "jq '.z' /config/nrg/output.json"
  value_template: "{{ value_json[0] }}"
  json_attributes:
  - 0
  - 1
  - 2

Thank you!
