Hello, I'm trying to upgrade a odoo 12 custom send email module to odoo 15 and I'm facing issues on sending emails. I followed a cybrosys tutorial on how to send email but what I see in logs is:

"2022-06-21 09:37:52,869 635822 INFO db15-4 odoo.addons.mail.models.mail_mail: Ignoring invalid recipients for mail.mail 942659108180984\\.1655804272\\.480145692825317\\-openerp\\-3\\-res\\.partner@dev15>:\\[\\]\\ "

Please\ follow\ this link as this editor adds backslashes.
