Getting error json.decoder.JSONDecodeError

Question

Here's the full traceback of the error I am getting:

ERROR 2022-11-08 13:29:54,959: HTTP POST /voice_chat/rooms 500 [0.32, 127.0.0.1:54258]

This is my code:

def post(self, request, *args, **kwargs):
    decode_request = request.body.decode("utf-8")
    print('decoded request body', decode_request)
    request_body = json.loads(decode_request)
    # print('request body', request_body)
    room_name = request_body.get("roomName")
    participant_label = request_body["participantLabel"]
    # print('username', curr_username)
    response = VoiceResponse()
    dial = Dial()
    dial.conference(
        name=room_name,
        participant_label=participant_label,
        start_conference_on_enter=True,
    )
    response.append(dial)
    return HttpResponse(response.to_xml(), content_type="text/xml")

Here is a sample of what I'm posting:

{"roomName":"testingUseremmanuelS21","participantLabel":"emmanuelS21","matchedUser":"testingUser"}

This is what I have in decode_request

AccountSid=***&ApiVersion=2010-04-01&ApplicationSid=***&CallSid=CAf4e

`decode_request` is not in json format and/or is empty, therefore `json.loads(decode_request)` throws an error. Show us the contents of that variable. — John Gordon, Nov 08 '22 at 19:42
@JohnGordon it definitely isn't empty, have added the contents of that variable to my question — Emm, Nov 08 '22 at 19:56
That isn't in json format. Why are you trying to call `json.loads()` on it? — John Gordon, Nov 08 '22 at 19:58
@JohnGordon It's sent to the backend as a JavaScript object and this is what I initially had with no errors (minus decode). Additionally, following this answer regarding how to parse 'request.body' https://stackoverflow.com/questions/29780060/trying-to-parse-request-body-from-post-in-django — Emm, Nov 08 '22 at 20:02
