bug

Why a Is Single doctype giving error when sending mail ?
Traceback here:

Is it actually possible to send mail from is_single doctypes or not or there’s some bug ??

Came to find that to send email, name myst be present but in is Single that name is same as doctype name that’s why it was giving error
