That message is coming from this line.

I'm guessing your config/initializers/wicked_pdf.rb looks something like this:

WickedPdf.config = {
  exe_path: 'xvfb-run -- /usr/bin/wkhtmltopdf'
}

which is currently not supported, as there are checks that make sure that string is a valid path to an executable file.

There is a PR to address this, but I'm not yet sure the benefits outweigh the risks of removing valuable error messages, and want to tweak it a bit.

A good workaround would be to create a new executable stub something like this:

echo echo '#!/bin/bash
xvfb-run -- /usr/bin/wkhtmltopdf' > bin/wicked_pdf
chmod +x bin/wicked_pdf

and change your initializer to point to this new file

WickedPdf.config = {
    exe_path: Rails.root.join('bin', 'wicked_pdf').to_s
}

Let me know how it goes!

I added the "$@":

echo '#!/bin/bash
xvfb-run -- /usr/bin/wkhtmltopdf  "$@"' > bin/wicked_pdf
chmod +x bin/wicked_pdf
