Members Module, attachment of the SendingEmailOnAutoSubscription model does not work.

Bug

During an online payment (Stripe, for example), the callback correctly triggers all actions and sends the welcome email to the new member. The invoice is also correctly created, even in PDF, but it is not attached. However, if I send it through the invoice module, then everything goes correctly, and the invoice is added to the email.
