Good day!

When sending an email, I send the following error:

odoo.addons.mail.models.mail_template: Failed to render template <Template memory:7fadd029d810> using values {'format_tz': <function <lambda> at 0x7fae1c138aa0>, 'ctx': {u'lang': u'es_MX', u'tz': u'Mexico/General', u'uid': 1, 'safe': False, u'journal_type': u'sale', u'params': {u'action': 229}, u'already_open': 1, u'type': u'out_invoice', 'tpl_partners_only': True}, 'user': res.users(1,), 'object': account.invoice(91,)}Traceback (most recent call last):

They could help me to solve the problem.
