[FIXED] Django returning 500 on POST request

Issue

So, I have this simple contact form, which Django handles by sending e-mails to me and to the person who contacted us. I've written an AJAX funcion to handle it. The only thing is that, no matter what I try, I keep getting an 500 status.

My Django (1.11) code:

def contato(request):
    if request.method == 'POST':
        name = request.POST['name']
        email = request.POST['email']
        phone = request.POST['phone']
        message = request.POST['message']
        newmessage = "Mensagem recebida de {}.\nTelefone: {}\ne-mail {}\n {}".format(name, phone, email, message)
        send_mail(
            'Nova mensagem pelo site',
            newmessage,
            'PLACEHOLDER@EMAIL',
            ['PLACEHOLDER@EMAIL'],
            fail_silently=False
        )
        send_mail(
            'Recebemos sua mensagem!',
            'Olá, {}!\nRecebemos sua mensagem e entraremos em contato em breve.'.format(name),
            'PLACEHOLDER@EMAIL',
            [email],
            fail_silently=False
        )
        return HttpResponse()

And here's my AJAX request:

form.addEventListener("submit", function(event) {
    event.preventDefault();
    let dadoscontato = {
        name: name.value,
        email: email.value,
        phone: phone.value,
        message: message.value,
        csrfmiddlewaretoken: document.getElementsByName('csrfmiddlewaretoken')[0].value
    };

    fetch('/contato/', {
        method: 'POST',
        credentials: 'same-origin',
        headers: {
            "X-CSRFToken": getCookie("csrftoken"),
            "Accept": "application/json",
            "Content-Type": "application/json"
        },
        body: JSON.stringify(dadoscontato),
    })
    .then(function(response){
        console.log(response)
        return response.json();
    })
    .then(function(response){
        alert('Mensagem enviada com sucesso!');
    });
});

Solution

Just to mark this question as solved:

I had to run a .decode() while loading the response. Everything works fine now.
