I get the following error after running odoo and accessing localhost:8069

   File "D:\Study\python_code\odoo_github\odoo-17.0\odoo\addons\base\models\ir_qweb.py", line 765, prints _generate_code

     raise QWebException("Error when compiling xml template",

odoo.addons.base.models.ir_qweb.QWebException: Error when compiling xml template

ValueError: forbidden opcode(s) in 'True': RETURN_CONST

Template: database_manager

Path: /html/body/div/div[4]/div/div/form/div[1]/t[1]

Node:


What is the cause and how to fix it?

Thanks

Hi,

When Odoo encounters a False expression during evaluation, it may throw a forbidden opcode error (from safe_eval.py) due to the newly introduced opcode in Python 3.12: RETURN_CONST. To resolve this issue, you can consider downgrading the Python version to 3.11.


Hope it helps
