Why do I get typeerror here?

Hello, I'm trying to get my code to give me information based on the id the user inputs.
For some reason I get the print corresponding with TypeError even though I input the correct number that does have data.
What's going on?

What I have tried:

This is my code:

from django.shortcuts import render, HttpResponse
import requests
from django.views.generic import FormView
from .forms import MonotributoForm
from app.ws_sr_padron import get_persona

class ConstanciaInscripcion(FormView):

    def get(self, request):
       return render(request, 'app/constancia-inscripcion.html')
    
    def post(self,request):

        form = MonotributoForm(request.POST)
            
        try:
           cuit_r = int(request.POST.get('cuit', '-1'))  # Get 'cuit' with default of -1
        except ValueError:
           print('try again')

        response =get_persona(cuit_r)

        try:
            nombre = response["persona"]["nombre"]
            apellido = response["persona"]["apellido"]
        except KeyError:
            nombre, apellido = None, None
            print("response is missing keys!")
        except TypeError:
            nombre, apellido = None, None
            print("response had wrong type!")
        else:
            print("nombre:", nombre)
            print("apellido:", apellido)

        if form.is_valid():
            cuit = form.cleaned_data.get('cuit')
            email = form.cleaned_data.get('email')
            cuit.save()
            email.save()
            return HttpResponseRedirect('app/constancia-inscripcion.html')


        return render(request, 'app/constancia-inscripcion.html')
