The %json variable get filled with this:

{
  "cod": "200",
  "message": 0,
  "cnt": 1,
  "list": [
    {
      "dt": 1604394000,
      "main": {
        "temp": 5.69,
        "feels_like": 1.68,
        "temp_min": 5.69,
        "temp_max": 5.99,
        "pressure": 1011,
        "sea_level": 1011,
        "grnd_level": 1008,
        "humidity": 81,
        "temp_kf": -0.3
      },
      "weather": [
        {
          "id": 802,
          "main": "Clouds",
          "description": "scattered clouds",
          "icon": "03d"
        }
      ],
      "clouds": {
        "all": 49
      },
      "wind": {
        "speed": 3.5,
        "deg": 196
      },
      "visibility": 10000,
      "pop": 0,
      "sys": {
        "pod": "d"
      },
      "dt_txt": "2020-11-03 09:00:00"
    }
  ],
  "city": {
    "id": 2636005,
    "name": "Thornaby",
    "coord": {
      "lat": 54.52,
      "lon": -1.3
    },
    "country": "GB",
    "population": 22356,
    "timezone": 0,
    "sunrise": 1604387520,
    "sunset": 1604420727
  }
}

What I would like to be able to do is getting simple values from the json. I tried doing that here

var parsedjson=JSON.parse(global('json'));
setLocal('test',parsedjson.cod);
flashLong(local('test'));

Not only isn't flashLong doing anything, when the last step of the task (flash) runs I only see "%test".

Also, to make sure, let's say I want to get "temp" from the json the regular syntax applies right?

parsedjson.list[0].main.temp

Can anyone help me understand why %test isn't being filled like I want it?

DISCLAIMER: I know about autotools. But I'd prefer to do it this way as I don't use autotools for anything else.

Taskers' globals starts with first capital letter. Should be:
var parsedjson=JSON.parse(global('json'));

I know its been awhile, but for whoever might come across this - Starting from version 5.12, tasker supports parsing JSON without the need of additional packages.

So, to get cod's value, you can just simply:

SetVariable:
    Name: %test_var
    To: %json.cod
    Structured Output: Checked

To get the temperature - set the variable to %json.list[0].main.temp
