Как устранить ошибку Bad Request 400 с помощью функции send_mail?

Я использую React frontend для отправки данных из контактной формы с реактивным рендерингом в Django backend, который отправляет данные в виде электронного письма. Однако я продолжаю получать ошибку 400 Bad Request. Я пытался использовать функцию send_mail в оболочке, но получаю эту ошибку: "socket.gaierror: [Errno 11001] getaddrinfo failed"

Contact.js

    const sendEmail = () => {
        const csrfCookie = Cookies.get('csrftoken');
        
        console.log(formValue);
        axios.post("contact/", formValue, {
            headers: {
                'X-CSRFTOKEN': csrfCookie,
            },
        })
            .then(response => {
                console.log(response);
            })
            .catch(error => {
                console.log(error);
            });
    };

    const handleSubmit = (event) => {
        event.preventDefault();
        sendEmail();
        setFormValue({
            name: "",
            email: "",
            message: "",
        });
    };
