I'm developing a custom module, I just started and coding the view I have a context error with my variables, how can I solve this, my view is inherited from product form view

<record id="view_product_form_inherit_property_view_form" model="ir.ui.view">
    <field name="name">property_management_system.property.view.form</field>
    <field name="model">property_management_system.property</field>
    <field name="mode">primary</field>
    <field name="inherit_id" ref="product.product_normal_form_view"/>
    <field name="arch" type="xml">
      <xpath expr="//div[@name='options']" position="inside">
        <div>
          <field name="property_ok"/>
          <label for="property_ok"/>
        </div>
      </xpath>
    </field>
  </record>

My model is inherits from product.product

class Property(models.Model):
    _name = "property_management_system.property"
    _inherit = ["product.product"]
    property_ok = fields.Boolean("Is Property")

I've been searched a lot and not getting answer, so I decide post this, I can't find wheres the problem.
