I’m encountering an issue when trying to send emails with PDF attachments. The email isn’t being sent, and I receive the following error code …

Traceback (most recent call last):
File “apps/frappe/frappe/email/doctype/email_queue/email_queue.py”, line 167, in send

It’s the PDF creation that is having a problem. Do you have any images in your print format ? If so, you’ll probably find that your hostname is not set correctly in your config, so the pdf generator cannot find a route to the image. wthtmltopdf will convert /path/to/your/image.png into http://domain/path/to/your/image.png … where domain is picked up from your config.

Sorry but it’s early morning so i can’t look at my system and tell you where the changes needs to be made. Maybe someone who is properly awake can take one with the details …

Good luck

@Kevin_Salt add "host_name": your domain . in site_config under /site/site_name .

Without editing a file directly, I think the command is …

Bench setup add-domain --site {yoursite} {your domain name}
