Prawn does not render a PDF on Heroku, but does it local

Question

As the title says: My PDFs are perfectly rendered when I run on my server locally, but on Heroku I get a NoMethodError. It seems that Heroku cannot find my prawn gem. I am using the prawn-rails gem.

Any ideas?

I have uploaded the complete callstack here: http://f.cl.ly/items/2g232h3U0B2G0k0i0S1y/Action%20Controller%20%20Exception%20caught.html

Does prawn require saving the pdf to disk before sending to client? — tybro0103, Jul 01 '11 at 20:44
You can definitely process PDFs with free Heroku. I do it with wkhtmltopdf-based WickedPDF on their 1.8.7 stack. — Felix, Jul 02 '11 at 00:37
agreed - the prawn site itself runs on Heroku!!! http://prawn.heroku.com/ — John Beynon, Jul 02 '11 at 07:15
It worked before they upgraded their stack and there are several other apps that use Prawn on Heroku. — d135-1r43, Jul 05 '11 at 09:02
The problem is in fact here `.bundle/gems/ruby/1.8/gems/prawn-0.11.1/lib/prawn/font/afm.rb:91:in \`normalize_encoding'`. So prawn is loaded and (partly) working. This may hint at a bug in prawn, though. — Koraktor, Jul 05 '11 at 09:06
Yes, I am using the free plan, but I have solved the problem as you can see in my own answer. — d135-1r43, Jul 18 '11 at 08:44

Solved. It seems as Heroku does not have a "Helvetica".
