Hi!

I have this problem when trying to install my module.

Here is my model file:

from odoo import models, fields, api, _
import logging

_logger = logging.getLogger(__name__)

class HrEmployee(models.Model):
    _inherit = 'hr.employee'
    address_home_id = fields.Char(string='Home Address')

During the installation there is an error:

Error:
Odoo Server Error
