Dear community, I had below error during my attempt to generate PDF. Does anyone know the solution for this?

Version: v12.9.3 (version-12)

Traceback (most recent call last):

    response = frappe.api.handle()

    return frappe.handler.handle()

I am having a similar issue with a brand new local installation. I hit the PDF button on a quote and I get the following error:

/usr/local/bin/wkhtmltopdf: error while loading shared libraries: libpng12.so.0: cannot open shared object file: No such file or directory

Check to see if you have this library installed…on debian, the command would be
dpkg -l | grep libpng

That was the problem.

I solved the issue by installing the latest version of wkhtmltopdf

I was having another issue with my logo in the letterhead but strangely that ended up being solved by converting the logo fie from .jpg to .png
