Hello,
I have been getting this error since I upgraded to Odoo v15 when I try to send & print an invoice:
Failed to render QWeb template : 'account.move' object has no attribute 'invoice_payment_state'
Traceback (most recent call last):
  File "/home/odoo/src/odoo/15.0/odoo/addons/base/models/qweb.py", line 219, in render_template
    yield from compiled_fn(self, values, log)
  File "", line 66, in template
AttributeError: 'account.move' object has no attribute 'invoice_payment_state'
Error when render the template
AttributeError: 'account.move' object has no attribute 'invoice_payment_state'
Template: 
Path: /div/div/p/t[7]
Node: )
Any idea on how to solve it ?
Thanks.
