Acredito que este módulo não funciona, pois não temos os arquivos "account_journal" e "account_move" devidamente criados.

Erro:

Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
File "D:\odoo\server\odoo\http.py", line 640, in _handle_exception
return super(JsonRequest, self)._handle_exception(exception)
File "D:\odoo\server\odoo\http.py", line 316, in _handle_exception
raise exception.with_traceback(None) from new_cause
ValueError: delivery.carrier.delivery_type: required selection fields must define an ondelete policy that implements the proper cleanup of the corresponding records upon module uninstallation. Please use one or more of the following policies: 'set default' (if the field has a default defined), 'cascade', or a single-argument callable where the argument is the recordset containing the specified option.

O erro ocorre no momento de instalar o módulo dos correios no odoo e somente com ele, fiz um fork da branch da versão 14 dos módulos do repositório e utilizei o delivery_correios de lá.
Desde já muito obrigado pelo suporte!

Não consigo identificar o erro, mas o módulo paghiper não funciona e retorna somente o erro "Items Inválidos".
Estou usando Odoo 14, mas acredito que não funciona em nenhuma versão.
