Error generating PDF

While sending an email with document, getting pdf error. Any suggestion.

Did you get any error traceback?

No traceback, getting only error as shared in post.

Is wkhtmltopdf installed?

Yes, wkhtmltopdf is installed. And pdf was getting generated earlier.
Environment:

  • Debian wizzy
  • Google cloud

i was experiencing the same error. pdf generation fails then sends it as html.

here is the solution

solved it with:

bench set-url-root {sitename} http://{hostname_that_resolves_the_site}

Example

bench set-url-root site1.local https://my.site.com

i found it here PDF Generation error - #4 by Heikki_Heer
