Ошибка счета-фактуры xml UBL2.1 на python с использованием шаблона блока django

Я получил эту ошибку, когда попытался проверить действительность xml-счета-фактуры

Ошибка в электронном счете-фактуре в формате UBL (Universal Business Language), которая связана с соблюдением требований к выставлению счетов, поэтому здесь я использую шаблон блока django, который вызывает функцию для создания xml-файлов из счетов-фактур в зависимости от ubl 2.1, я получил ошибку, когда пытался проверить действительность из xml-счета-фактуры ... может ли кто-нибудь помочь

вот код шаблона

{% comment %} {% for discount in  %} {% endcomment %}
{% if invoice.allowance_discount %}
    <cac:AllowanceCharge>
        <cbc:ID>1</cbc:ID>
        <cbc:ChargeIndicator>false</cbc:ChargeIndicator>
        <cbc:AllowanceChargeReason>discount</cbc:AllowanceChargeReason>
        <cbc:Amount currencyID="{{ invoice.currency.code }}">{{ invoice.allowance_discount|default:"0.0"|floatformat:2 }}</cbc:Amount>
        <cac:TaxCategory>
            <cbc:ID schemeAgencyID="6" schemeID="UN/ECE 5305">{{ invoice.company.finance_company.account_sale_tax.vat_category_code }}</cbc:ID>
            <cbc:Percent>{{ invoice.company.finance_company.account_sale_tax.amount|default:"0.0"|floatformat:2 }}</cbc:Percent>
            <cac:TaxScheme>
                <cbc:ID schemeAgencyID="6" schemeID="UN/ECE 5153">VAT</cbc:ID>
            </cac:TaxScheme>
        </cac:TaxCategory>
    </cac:AllowanceCharge>
{% endif %}
{% comment %} {% endfor %} {% endcomment %}`
