[17.0] l10n_es_facturae_face error zeep.exceptions.ValidationError: Expected at least 1 items (minOccurs check)

[metaOkami]

Buenos días, estoy intentando configurar y usar el módulo de envío de facturas a FACe, y me he encontrado con varios problemas:

Por un lado, configurando el módulo tal y como insinua el readme.rst, al intentar enviar una factura me daba el siguiente error en el job del envío edi:

Decir, que subí el certificado tanto a https://se-integradores-face.redsara.es/inicio como a Odoo e igualmente seguía sin funcionar. Abrí un ticket al soporte de FACe sobre si el link del servicio era correcto o si me tenía que dar de alta en algún sitio más y me contestaron esto:

Dejo los links por aquí:

Decidí finalmente probar con el ws https://se-face-webservice.redsara.es/facturasspp?wsdl ya que era el que más se parecía a lo que hay puesto como ws de test en el readme, y ahora me responde este error, que no consigo saber a qué se debe:

En conclusión, me gustaría que me confirmaseis si el link de el ws tanto de test como de producción que hay en el readme es usable, y en caso de que el readme esté equivocado, sería vital un pull request al respecto. En cualquier caso, por qué pueden estar dando estos errores? No he tenido mucho tiempo de revisar el código y de todas formas no veo nada raro...Puede ser que me falte configurar algo?
