[solved] Interactive Dialog Submission is empty

I am creating a simple integration that invokes an Interactive Dialog in response to when a user types a Slash Command, which is working fine. I somehow cannot get the form submissions on the backend, the submission key is empty in response, I’ll post the code below

This is the JSON I return to Mattermost from the backend when a slash command is executed:

{
    "trigger_id": request.GET['trigger_id'],
    "url": "https://0dc80a84.ngrok.io/hello/",
    "dialog": {
        "callback_id": "somecallbackid",
        "title": "Test Title",
        "icon_url": "http://www.mattermost.org/wp-content/uploads/2016/04/icon.png",
        "elements": [
            {
                "display_name": "One",
                "name": "wins",
                "type": "textarea",
                "placeholder": "Wins"
            },
            {
                "display_name": "Two",
                "name": "setbacks",
                "type": "textarea",
                "placeholder": "Setbacks"
            },
            {
                "display_name": "Three",
                "name": "Mood",
                "type": "select",
                "help_text": "1 for lowest, 5 for highest",
                "placeholder": "1 for lowest, 5 for highest",
                "optional": False,
                "options": [
                    {
                        "text": "1",
                        "value": "1"
                    },
                    {
                        "text": "2",
                        "value": "2"
                    },
                    {
                        "text": "3",
                        "value": "3"
                    },
                    {
                        "text": "4",
                        "value": "4"
                    },
                    {
                        "text": "5",
                        "value": "5"
                    }
                ]
            }
        ],
        "submit_label": "Submit",
        "notify_on_cancel": False,
        "state": "somestate"
    }
}

And this is my backend code snippet:

@csrf_exempt
def hello(request):
    print(request.POST.get("submission", None))
    return JsonResponse({
        "text": "Hello"
    })

This prints None. Any pointers?

@amy.blais this is resolved. It was a logical error on my end. Please remove this.
