I'm building a custom module for email templates for HR. My template file (hr_mail_template_mail_templates.xml) is this one:

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

<odoo>

<data>

<field name="name">Work Permit Expiry Reminder</field>

<field name="subject">Your Work Permit Expires Soon</field>

<![CDATA[

Dear ${object.name},

This is a reminder that your work permit is set to expire on ${object.work_permit_expiration}.

Please update your documents as soon as possible.

Regards, HR Department

</field>

<field name="email_to">${object.work_email}</field>

<field name="email_from">${user.email}</field>

</record>

<field name="name">Performance Review Notification</field>

<field name="subject">Upcoming Performance Review</field>

<![CDATA[

Hello ${object.parent_id.name},

Please be reminded that ${object.name}'s performance review is due soon.

Kindly schedule the evaluation accordingly.

Best regards, HR Department

</field>

<field name="email_to">${object.parent_id.work_email}</field>

<field name="email_from">${user.email}</field>

</record>

</data>

</odoo>

When I try to activate the custom, show this error:

The suggested way of using variables in a template is to t-out' them (older versions of Odoo may require the use of t-esc instead).

Also, assigning values to fields should be done within using the {{ x }} notation, rather than ${x}.
