Cannot send email from Document with Attachment as regular user - Not showing to Email Queue

Frappe Framework Permissions
2

I thought maybe this is the issue: From Send emails from ERPNext from own account - #2 by umair by @umair :

To allow Users to send emails from your ERPNext account, you should ensure that Roles assigned to those Users also cover Email permission on that Doctype.

Update: It seems this is not the issue, as the user:

  • tries to send Purchase Invoice document
  • has roles of Accounts User (which allows Email-ing Purchase Invoice) and also Purchase Manager

If the “Email” permission is not given in the role, then the “Email” menu item will not be shown in the first place.
