I can't load my module, becuase it is trying to search for an xpath location in apps settings, and my module is meant for the website_sales app. So, I have 2 questions

1) Is something wrong with my code

2) Is there a way to limit module's functionality only to specific url? (e.g. 127.0.0.1/shop)

Error log when I try to press "Upgrade", to update the edited module - https://pastebin.com/6mjgk38g

Template code:

<odoo>
    <data>
       <template id="website_sales_inh" name="webiste_sales_inherit" inherit_id="website_sale.products_item">
          <xpath expr="//span[@data-oe-model='product.template' and @data-oe-id='2' and @data-oe-field='image_1920' and @data-oe-type='image' and @data-oe-expression='product.image_1920' and @class='d-flex h-100 justify-content-center align-items-center']" position="inside">
             <input name="testing our site" t-att-value="1234" type="hidden"/>            
          </xpath>
       </template>
    </data>
</odoo>

Model code:

# -*- coding: utf-8 -*-

from odoo import models, fields, api


class imgtogif_r(models.Model):
    _inherit = 'product.product'
    _name = 'product.product'
