Hi,

The error "The field 'hide_peppol_fields' does not exist in the model 'res.partner'" typically occurs after migration if custom fields weren't handled properly.

There are two ways to fix this:

Add the missing field back in your custom module if it's still needed:

python:

from odoo import models, fields

class ResPartner(models.Model):

    _inherit = 'res.partner'

    hide_peppol_fields = fields.Boolean(string="Hide PEPPOL Fields")

Then upgrade the module:

    ./odoo-bin -u your_module_name -d your_database

Remove the field reference from all views and code if it's no longer required (e.g:in XML: <field name="hide_peppol_fields"/>), then upgrade the module as above.

Either approach will fix the error depending on whether you still use the field.

Hope it helps.

The below method will help you to fix this issue:

Step 1 : Settings -> Technical -> Views(User Interface) -> Search res.partner (model)

Step 2 : Delete all the res.partner model views 

Step 3 : Upgrade 'Base' Module again. 

Step 4 : Upgrade your custom module.
