Hi, I'm Using Odoo 13 Enterprise

When i create a ticket through Helpdesk module without an attachment, it's working fine

But if i attach an attachment this error will pop up

The log:

Traceback (most recent call last):

I think this is a bug, similar to this https://github.com/odoo/odoo/issues/38559
But since there is still no answer i had to ask here.

Thanks
