Help Needed: Error with PDF Generation when Sending Email

[edardev]

Hello, community!

I’m encountering an issue while trying to send an email through a Gmail account. The process fails with the error shown below. It seems related to generating a PDF, possibly due to broken image links or network restrictions. Has anyone faced a similar problem or know how to resolve this?

During handling of this error, a ValidationError is raised:

frappe.exceptions.ValidationError: PDF generation failed because of broken image links

It looks like the PDF generation might be failing due to inaccessible image URLs. If anyone has suggestions or a solution for this issue, I’d greatly appreciate your help!

Thank you in advance!

Wkhtmltopdf layout error

Hi @jodeq, there can be different reasons that can lead to this. I would guess that wkhtmltopdf cannot access the references resources (CSS and imgs). This can be caused e.g. by a firewall blocking these intra-zone calls the hostname configuration of ERPNext (see site/site1.local/site_config.json should contain "host_name": "https://www.yourdomain.com",) by a missing libssl1.0-dev (normally missing in Debian 9) You can also troubleshoot by extracting the html that goes to wkhtmltopdf by temp…

I’m still facing the issue, even after adding host_name to both site_config.json and common_site_config.json during the site creation in the docker-compose setup.

echo "sites/common_site_config.json found";
       bench new-site --no-mariadb-socket --admin-password="${ADMIN_PWD}" --db-root-password="${DB_ROOT_PWD}" --install-app erpnext --set-default "${SITE_NAME}";
       bench set-config -g host_name "https://${SITE_NAME}";
       bench --site "${SITE_NAME}" set-config host_name "https://${SITE_NAME}";

And the libssl-dev is installed:

I had the same problem. I was tweaking many configurations with- and without the https:// in the site_config and also setting my /etc/hosts for my own domain to 127.0.0.1…

I can not remember what worked in the end, but play around with these, I hope this help, but I am not sure…
