A little help with RESTful integration

Configuration
1

Assuming the REST response below:

{
    "alert": [],
    "amps": [],
    "cloud": {},
    "connections": {
        "LISTEN": 68,
        "ESTABLISHED": 261,
        "SYN_SENT": 0,
        "SYN_RECV": 0,
        "initiated": 0,
        "terminated": 0
    },
    "processlist": [
        {
            "pid": 8368,
            "cpu_times": [
                3.140625,
                224.3125,
                0,
                0
            ],
            "cmdline": [
                "C:\\Users\\MKANET\\AppData\\Local\\Programs\\Python\\Python310\\python.exe",
                "C:\\Users\\MKANET\\AppData\\Local\\Programs\\Python\\Python310\\Scripts\\glances.exe",
                "-w",
                "-0",
                "--disable-autodiscover",
                "--disable-plugin",
                "docker",
                "--config",
                "C:\\Users\\MKANET\\AppData\\Local\\Programs\\Python\\Python310\\scripts\\glances.conf",
                "-q"
            ],
            "username": "TITAN\\MKANET"
        },

I would like to capture the first 2 lines listed in "cmdline":[ ]. Below, is my best attempt at doing this; which is wrong. It only displays the first line as the sensor state, It doesn’t list the 2 lines as attributes in this sensor.

rest:
  - resource: http://192.168.1.55:61208/api/3/all
    sensor:
      - name: process_0_cmdline
        value_template: '{{ value_json.processlist.0.cmdline.0 | default }}'
        json_attributes_path: "$.processlist.0.cmdline.[0,1]"
        json_attributes:
          -[0]
          -[1]
2

I was finally able to get the information I was looking for. I ended up capturing the first 2 lines as the sensor state by using the below code:

rest:
  - resource: http://192.168.1.55:61208/api/3/all
    sensor:
      - name: process_0_cmdline
        value_template: '{{ value_json.processlist.0.cmdline.0,value_json.processlist.0.cmdline.1 | default }}'
        json_attributes_path: "$.processlist.0.cmdline.[0,1]"

sensor.process_0_cmdline State value:

('C:\\Users\\MKANET\\AppData\\Local\\Programs\\Python\\Python310\\python.exe', 'C:\\Users\\MKANET\\AppData\\Local\\Programs\\Python\\Python310\\Scripts\\glances.exe')
