Help Debug Command_Line Sensor Value_Template

1

Moving everything to the new command_line structure and something that has worked now doesn’t. I’m reading statistics from my unifi controller using this:

  - sensor:
      name: udm_unifios
      command: !secret udm_unifios
      value_template: |-
      {% set json = value_json.data[0] %}
      {{ json["system-stats"].cpu }}|
      {{ json.temperatures[1].value | round(1) }}|
      {{ json["system-stats"].mem }}|
      {{ ((json.storage[1].used / json.storage[1].size) * 100) | round(1) }}|
      {{ json.internet }}|
      {{ json.startup_timestamp | timestamp_local }}|
      {{ json.displayable_version }}|
      {{ json.upgradable }}
      scan_interval: 120

And it does not like the line:

{% set json = value_json.data[0] %}

I’m getting this error:

Error loading /config/configuration.yaml: while scanning for the next token
found character ‘%’ that cannot start any token
in “/config/include/command_line.yaml”, line 18, column 8

Does the value_template work differently in the command_line integration or am I just completely wrong in assuming it ever worked?

P.S. Tested and receiving valid JSON:

{
  "meta": {
    "rc": "ok"
  },
  "data": [
    {
      "port_table": [
        {
          "port_idx": 1,
          "speed_caps": 1048623,
          "op_mode": "switch",
          "forward": "all",
          "attr_no_edit": true,
          "autoneg": true,
          "enable": true,
          "flowctrl_rx": false,
          "flowctrl_tx": false,
          "full_duplex": true,
          "is_uplink": true,
          "jumbo": false,

etc

Indent all of your template lines two spaces.

      value_template: |-
        {% set json = value_json.data[0] %}
        {{ json["system-stats"].cpu }}|
        {{ json.temperatures[1].value | r etc...
