MultiValueDictKeyError в / upload /

Question

Мне нужна помощь с Django, я продолжаю сталкиваться с MultiValueDictKeyError, когда нажимаю кнопку загрузки. И это показывает MultiValueDictKeyError в / upload / 'my_file', но не уверен, как решить эту проблему после нескольких попыток. Ниже приведены мои коды для моделей, просмотра и страницы шаблона. Для вашего совета, пожалуйста.

files_ul_dl.html

    <form method="post" enctype="multipart/form-data">{% csrf_token %}
                <input type="file" name="my_file">
                <button class="btn btn-secondary" type="submit">Upload</button>
            </form>
        </div>
        <hr>

        <h4>File Type Count</h4>
        <table class="table">
          <thead>
            <tr>
                {% for file_type in file_types %}
                    <th scope="col">{{ file_type }}</th>
                {% endfor %}
            </tr>
          </thead>
          <tbody>
            <tr>
                {% for file_type_count in file_type_counts %}
                    <td>{{ file_type_count }}</td>
                {% endfor %}
