Description of the issue
I found out an issue in Point of Sale using Tax-Rate.
Basically when I add a product with a defined tax in my basket and I’m going to checkout it I got following error:
AttributeError: 'NoneType' object has no attribute 'fieldtype' Possible source of error: erpnext (app)
Context information (for bug reports)
Digging inside code I found out the issue.
The function def update_itemised_tax_data(doc) in /frappe-bench/apps/erpnext/erpnext/regional/italy/utils.py is making an assignment in line 27 row.tax_rate = flt(tax_rate, row.precision("tax_rate")).
The call function row.precision("tax_rate") has its definition def precision(self, fieldname, parentfield=None) -> int | None in /frappe-bench/apps/frappe/frappe/model/base_document.py in line 1133.
At line 1155 (same function) basically we got this issue.
In this particular circumstances df = frappe.get_meta(doctype).get_field(fieldname) is None and it create the error in the next if statement at line 1157: if df.fieldtype in ("Currency", "Float", "Percent"):
Steps to sort the issue
To sort this annoying issue we need to apply changes at /frappe-bench/apps/frappe/frappe/model/base_document.py.
We need to check the existence of df in the if statement at line 1157: if df and df.fieldtype in ("Currency", "Float", "Percent"):
