自定义报告中的Odoo 12 NonType错误

Question

我正在尝试在Odoo 12下创建一个自定义报告，以将其添加到“订单视图”下的打印选项。到目前为止，一切顺利，我将XML包含在清单中，并在sale_management / report文件夹下创建XML。我在编辑时更新了模块，并且已正确编译。但是，一旦按下打印按钮，就会出现此错误：

Error:
Odoo Server Error

During handling of the above exception, another exception occurred:

出于测试目的，XML几乎与名为sale_report_templates.xml]的同一目录中已经包含的模板完全相同，而我的整个文件为：

<?xml version="1.0" encoding="utf-8"?>

        <report
            id="albaran_sin_valorar"
            string="Documento sin valorar"
            model="sale.order"
            report_type="qweb-pdf"
            name="sale_management.report_albaran_sin_valorar"
        />

<template id="report_albaran_sin_valorar" inherit_id="sale.report_saleorder_document">

            <table class="table table-sm">
                <thead>
                    <tr>

                        <th t-if="has_option_discount" groups="sale.group_discount_per_so_line" class="text-lef$
                        <th class="text-right">Unit Price</th>
                    </tr>
                </thead>
                <tbody class="sale_tbody">
                    <tr t-foreach="doc.sale_order_option_ids" t-as="option">
                        <td>
                            <span t-field="option.name"/>
                        </td>
                        <td t-if="has_option_discount" groups="sale.group_discount_per_so_line">
   ...
   </template>
   </odoo>
我的问题是：-当然是什么问题。-该问题涉及Odoo的内在因素，因此我可以完全理解它

谢谢何塞
