How I can set the "square meter" as the default unit of measure automatically?

Frappe Framework
1

My decision was very simple:
in file hooks.py i configure function after_install:

…
after_install = "default_settings.stock_settings.default_square_meters"
…
In file stock_settings.py I created functions:

def set_default_unit(unit):
        doc = frappe.get_doc({"doctype": "Stock Settings"})
        doc.stock_uom = unit
        doc.save()


def default_square_meters():
      set_default_unit("Square Meter")

…

But when docker install all applications, it gives me the next exception:

frappe.exceptions.LinkValidationError: Could not find Default Stock UOM: Square Meter

How I can fix it or is exist another way of realization of this case?

could you set the default using customize form instead? You could export customization to an app after your done.
