Odoo 13: field 'product_uom_category_id' does not exist

This is my view:

<record id="view_order_form_inherit_sale_stock" model="ir.ui.view">
    <field name="name">sale.management.order.form</field>
    <field name="model">sale.order</field>
    <field name="inherit_id" ref="sale_stock.view_order_form_inherit_sale_stock"/>
    <field name="arch" type="xml">
        <xpath expr="//group[@name='sale_shipping']" position="attributes">
            <attribute name="invisible">1</attribute>
        </xpath>
    </field>
</record>

This is the error:

ValueError: Veld 'product_uom_category_id' bestaat niet

Fout context:
Weergave`sale.management.order.form`

The field product_uom_category_id is a default one in Odoo 13? It's in the sale & sale_management addon modules

This is their declaration

So yeah, i'm stuck. What i've tried:

<xpath expr="//field[@name='product_uom_category_id']" position="replace" /> in the view
in another model declaration:

_inherit = "sale.order.line" product_uom_category_id = fields.Many2one('uom.category')

What i've checked:

models/init.py has correct models imported
init.py has from . import models
manifest.py has correct dependencies

"depends": [ "base", "sale", "sale_subscription", "sale_management", "sale_stock", "account", "product", "stock", "mail", "sale_stock", "telsmart_invoice_add_order_to_invoice", ],

Should I use the model sale.order.line? It sounds wrong, since the 'base' model is sale.order, but the field appears in sale.order.line which is already in the view

I have no more things to try. Your help is mutch appreciated!

Solution

Found after 4 days: It was another Model that used order_line.product_uom_category_id In that model, there was no product_id present. Which is weird, since that model did not inherit from sale.order.line
