The incoming email server (Gmail) cannot properly process XML files attached to emails, resulting in a "RuntimeError: object unbound". This means invoices are not available in the Accounting module eventhough the incoming email server is properly setup following Odoo Docs and the scheduled action "Mail: Fetchmail Service"  is executed.


Log Sample:

- odoo.addons.l10n_cl_edi.models.fetchmail_server: Processing attachment PAQ_RECEP_R76382847-6_T33F25320270.xml
- odoo.addons.l10n_cl_edi.models.fetchmail_server: object unbound
-  odoo.addons.l10n_cl_edi.models.fetchmail_server: Failed to process mail from imap server DTE incoming.
