Sales invoice import on erpnext cloud returns error - quantity cannot be zero

Information about bug

I have ordered a trial ERPNext cloud system. I have entered 3-4 invoices (sales invoices) with already existing data (product, customer,etc). I tried to test the import of transactions from file.

So I do the following steps: Navigate to import/export: https://testYYYY.erpnext.com/app/data-import/

I chosed to download template with data (5 transactions and all required fields). Then I clear the values in ID column in order during the import to create new sales invoice transactions. Whatever format I choose (csv or Excel) , when I upload the file back I get the following error:

"Invalid Quantity Row #1: Item quantity cannot be zero"

Traceback (most recent call last): File "apps/frappe/frappe/core/doctype/data_import/importer.py", line 149, in import_data doc = self.process_doc(doc) ^^^^^^^^^^^^^^^^^^^^^ File "apps/frappe/frappe/core/doctype/data_import/importer.py", line 251, in process_doc return self.insert_record(doc) ^^^^^^^^^^^^^^^^^^^^^^^ File "apps/frappe/frappe/core/doctype/data_import/importer.py", line 270, in insert_record new_doc.insert() File "apps/frappe/frappe/model/document.py", line 291, in insert self.run_before_save_methods() File "apps/frappe/frappe/model/document.py", line 1091, in run_before_save_methods self.run_method("validate") File "apps/frappe/frappe/model/document.py", line 962, in run_method out = Document.hook(fn)(self, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "apps/frappe/frappe/model/document.py", line 1322, in composer return composed(self, method, *args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "apps/frappe/frappe/model/document.py", line 1304, in runner add_to_return_value(self, fn(self, *args, **kwargs)) ^^^^^^^^^^^^^^^^^^^^^^^^^ File "apps/frappe/frappe/model/document.py", line 959, in fn return method_object(*args, **kwargs) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "apps/erpnext/erpnext/accounts/doctype/sales_invoice/sales_invoice.py", line 266, in validate super().validate() File "apps/erpnext/erpnext/controllers/selling_controller.py", line 29, in validate super().validate() File "apps/erpnext/erpnext/controllers/stock_controller.py", line 52, in validate super().validate() File "apps/erpnext/erpnext/controllers/accounts_controller.py", line 171, in validate self.validate_qty_is_not_zero() File "apps/erpnext/erpnext/controllers/accounts_controller.py", line 1094, in validate_qty_is_not_zero frappe.throw( File "apps/frappe/frappe/__init__.py", line 645, in throw msgprint( File "apps/frappe/frappe/__init__.py", line 610, in msgprint _raise_exception() File "apps/frappe/frappe/__init__.py", line 561, in _raise_exception raise exc erpnext.controllers.accounts_controller.InvalidQtyError: Row #1: Item quantity cannot be zero

Then I decided to download all fields and upload them back (just clear the ID field in order to create new sales invoice the same as downloaded one with the template). I get the same error:

"Invalid Quantity Row #1: Item quantity cannot be zero"

The quantity fields are filled with values. Seems like the error is somewhere else reflecting at the end of this error.
