Hello

1. it this field o2m or m2m

2. Did you upgrade module sir ?

Hi,

To fix this, make sure the new field is added to the res.partner model. Then, upgrade the module to update the database schema.

You can upgrade the module from the terminal with this command:

odoo-bin -c /path/to/your/odoo.conf -d db_name -u module_name

Replace '/path/to/your/odoo.conf' with the path to your Odoo configuration file, 'db_name' with the name of your database, and 'module_name' with the name of the module you are upgrading.

Hope it helps
