Hey, folks.

I have been trying to create send a notification through email whenever a new maintenance request is created with logistics_type: Inbound. I have gone through a few issues here. If I do something like: Action --> Duplicate: and save a new record, it's basically working and sending email while if I try to create a new maintenance record through "create" button it's failing to render template with following error code:

Failed to render template <Template memory:7f7a88d4cf28> using values {'format_date': <function MailTemplate._render_template.<locals>.<lambda> at 0x7f7a81279730>, 'format_tz': <function MailTemplate._render_template.<locals>.<lambda> at 0x7f7a81279f28>, 'format_amount': <function MailTemplate._render_template.<locals>.<lambda> at 0x7f7a81279488>, 'user': res.users(2,), 'ctx': {'email_to': 'admin@rsaworks.com', 'safe': False}, 'object': None}

UndefinedError: 'None' has no attribute 'equipment_id'

my model:

class MaintenanceRequest(models.Model):

    _inherit = 'maintenance.request'

    @api.model

    def create(self, vals):

        res = super(MaintenanceRequest, self).create(vals)

        vals = {}

        if res.logistics_type == 'Inbound':

            if res.message_partner_ids:

                for follower in res.message_partner_ids:

                    vals.update({

                    'email_to': follower.email,

                    })

                    template_id = self.env.ref("ssi_maintenance.maintenance_email_notification_template").id

                    template = self.env['mail.template'].browse(template_id)

                    template.with_context(vals).send_mail(self.id, force_send = True)

        return res

and here is my email template:

<?xml version="1.0" encoding="utf-8"?>
