I just installed ERPNext and I get the above error when trying to send an invoice out.
It pops up while typing the email address but the email is still delivered. I tried to click on report issue but nothing seems to happen.
Any suggestions will help greatly.
Did you import the contacts you use?
Thanks for the favorable feedback.
No. I think the contact is from my user list. it was a fresh import with no imports.
Is this the latest version of frappe and erpnext?
Yes it is. 11.x.x (develop)
Latest Update solved my problem .Just bench update. Don’t know how but it does not matter.
