'NoneType' object is not subscriptable in django rest framework

Question

Im trying to receive data in json format in django restframework and utilize the data immediately but i realize i get error that 'NoneType' object is not subscriptable' and i feel that i need to use cleaned_data but i dont know how to use cleaned_data in rest framework...here is my code:

@api_view(['GET', "POST"])
def home(request):
    if request.method == 'POST':     
        name = request.data.get('name')
        email = request.data.get("email")
        amount = request.data.get("amount")
        phone = request.data.get("phone")

        return redirect(str(process_payment(name, email, amount, phone)))
    else:    
        responseData = {  
            "Homepage": "Payment"
        }
        return Response(responseData)

Here is my traceback error:

You should include the code for `process_payment`. Why are you converting that outcome using `str`? Have you checked whether one of the four variables is `None` before being passed to `process_payment`? — Wouter, Oct 11 '21 at 14:51
Did you try the suggestions [here](https://stackoverflow.com/questions/8949252/why-do-i-get-attributeerror-nonetype-object-has-no-attribute-something?r=SearchResults&s=2|143.5901), [here](https://stackoverflow.com/questions/18866657/nonetype-object-is-not-subscriptable?r=SearchResults&s=5|107.1203), or other posts with "NoneTpye" is not subscriptable? — marcel h, Oct 11 '21 at 14:52
@Wouter when i included the code of `process_payment`, the error persisted...If i print the variables, im getting exactly what i inputed but still, it tells me that 'NoneType' object is not subscriptable' — Oladipo, Oct 11 '21 at 15:10
@marcelh Ive checked the questions, ive checked djangorestframework docs still its not working — Oladipo, Oct 11 '21 at 15:11

I have fixed it. I printed the response at the process payment to see the error message, so I got:

{'status': 'error', 'message': 'Invalid authorization key', 'data': None}

I now remember that I altered my secret key in the morning, so I got it from my dashboard and made the necessary corrections and everything started working.

Wrong answer: Just replace request.data to request.POST

Edited

I see your traceback and found that the problem is in line 55 of your views.py where you use response['data']. It is None!

When I tried this `name = request.POST.get(('name'))` and did `print(name)` to see if it firstly get the data, it returned None – Oladipo Oct 11 '21 at 15:16
Please check your sent request in your browser developer tools, network tab. Check and see what is your sent post data. – mrash Oct 11 '21 at 15:19
all im getting is this : POST http://localhost:8000/ 500 (Internal Server Error)....Im not getting any specific posted data – Oladipo Oct 11 '21 at 15:33
Check your request. 500 error is the response – mrash Oct 11 '21 at 15:45

Very good. Now you click on the network at the right top of page and find the 500 error request. I think it is the first request. Click on it and see the request tab. – mrash Oct 11 '21 at 16:11

Ok, refresh page to see the request – mrash Oct 11 '21 at 16:39
