This issue is occurring when the user tries to add a VAT number while creating a new contact To reproduce this issue: 1) Install "contacts" and "partner_autocomplete" 2) Create a new contact from 'Contacts' 3) Give a valid VAT number e.g:- "SK2120312645" 4) Traceback occurs in the terminal Error:- "IndexError: list index out of range" https://github.com/odoo/odoo/blob/382b64c2f14073cfff1a8ef9290b5c7834d52188/addons/partner_autocomplete/models/res_partner.py#L143-L156 In some cases, the expected "zip_city" value is not at the last of the address list , which leads to a traceback. After applying this commit will resolve this issue by searching "zip_city" based on regex. sentry-5058467547 closes odoo/odoo#158580 X-original-commit: 55c605f44d3a4f280946f1c1fec3f5e1534b4ef9 Signed-off-by: Louis Baudoux (lba) <lba@odoo.com> Signed-off-by: Altaf Shaik (alsh) <alsh@odoo.com>
