Hi All,

I am facing issue while sending email. PFB error

FYI if I open the queue and click send it is working while sending through the scheduler facing issue.

  File "/home/mgmtapp/frappe/frappe-bench/apps/frappe/frappe/email/doctype/email_queue/email_queue.py", line 167, in send
    message = ctx.build_message(recipient.recipient)
  File "/home/mgmtapp/frappe/frappe-bench/apps/frappe/frappe/email/doctype/email_queue/email_queue.py", line 315, in build_message
    message = self.include_attachments(message)
  File "/home/mgmtapp/frappe/frappe-bench/apps/frappe/frappe/email/doctype/email_queue/email_queue.py", line 392, in include_attachments
    print_format_file = frappe.attach_print(**attachment)
  File "/home/mgmtapp/frappe/frappe-bench/apps/frappe/frappe/__init__.py", line 2225, in attach_print
    else get_print(doctype, name, **kwargs)
  File "/home/mgmtapp/frappe/frappe-bench/apps/frappe/frappe/__init__.py", line 2184, in get_print
    return get_pdf(html, options=pdf_options, output=output) if as_pdf else html
  File "/home/mgmtapp/frappe/frappe-bench/apps/frappe/frappe/utils/pdf.py", line 90, in get_pdf
    filedata = pdfkit.from_string(html, options=options or {}, verbose=True)
  File "/home/mgmtapp/frappe/frappe-bench/env/lib/python3.10/site-packages/pdfkit/api.py", line 75, in from_string
    return r.to_pdf(output_path)
  File "/home/mgmtapp/frappe/frappe-bench/env/lib/python3.10/site-packages/pdfkit/pdfkit.py", line 201, in to_pdf
    self.handle_error(exit_code, stderr)
  File "/home/mgmtapp/frappe/frappe-bench/env/lib/python3.10/site-packages/pdfkit/pdfkit.py", line 155, in handle_error
    raise IOError('wkhtmltopdf reported an error:\n' + stderr)

Please help to resolve the issue.

Hmm, I think I encountered the same problem once, but I don’t remember what the issue was. It be worth it to take a look at the Print Format, and check that there are no private files/inaccessible files.

There is also a bench/logs/wkhtmltopdf.log file

I couldnt able to resolve this issue. Getting error while sending the entire doctype

Thanks for the response,
Could you please let me know is this solution applicable for the prod instance as well i.e., by adding the “host_name”:“http://127.0.0.1:8000” to the site config file

No in production you check only wkhtmltopdf version is 12.6 with (patch qt) or not
