Expected singleton: res.users() when create new invoice programmatically Odoo 15

Question

I'm trying to create a new invoice in controller:

request.env['account.move'].sudo().create([
{
'move_type': 'out_invoice',
'journal_id': 1,
'invoice_date': '2020-01-10',
'invoice_line_ids': [(0, 0, {'product_id': 21, 'price_unit': 1000.0})],
}])
But i got this error
Expected singleton: res.users()
Please help, thanks.

I've found the answer with the help of my leader, here it is:
This issue is because we missing " self.env.user ", None [1]  to do this, we must add .with_user(SUPERUSER_ID) after model call.
Example:

from odoo import SUPERUSER_ID
request.env['account.move'].with_user(SUPERUSER_ID).sudo().create([
{
'move_type': 'out_invoice',
'journal_id': 1,
'invoice_date': '2020-01-10',
'invoice_line_ids': [(0, 0, {'product_id': 21, 'price_unit': 1000.0})],
}])
