ActionView::Template::Error: 403 Forbidden on Heroku

[ahanmal]

Everything was working fine on my Local and on my Heroku dev environment. Pushed to staging, and now I'm getting this error: ActionView::Template::Error: 403 Forbidden. Emptied the remote repo and repushed - same error.

Here is the stack trace:

It appears this is somehow having trouble reading an asset using open-uri within wicked_pdf_stylesheet_link_tag, where it is trying to read in a stylesheet over the internet, eventually leading to https://github.com/mileszs/wicked_pdf/blob/master/lib/wicked_pdf/wicked_pdf_helper.rb#L120

What does that wicked_pdf_stylesheet_link_tag call look like in your app? Is the stylesheet on a remote host? Does it work with a regular stylesheet_link_tag?

[ahanmal]

This is the direct code from my app:

<!doctype html>
<html>
<head>
    <meta charset='utf-8' />
    <%= wicked_pdf_stylesheet_link_tag "documents-pdf" -%>
</head>
<body>
    <div id="pdf-header">
    <%= params[:debug].present? ? image_tag('documents/vocabulist_black.jpg') : wicked_pdf_image_tag('documents/vocabulist_black.jpg') %>
        <h2 id="pdf-title"><%= @document.title %></h2>
    </div>
    <div id="pdf-content">
        <br>
        <br>
        <table>
            <tbody>
                <% @document.words.each do |word| %>
                <tr>
                    <td>
                        <%= word %>
                    </td>
                    <td>
                        <%= @document.dictionary[word] %>
                    </td>
                </tr>
                <% end %>
            </tbody>
        </table>
    </div>
</body>
</html>

The assets are on Cloudfront on the staging server, while on the development server, they are served by rails. That might be the problem. Ideas?

[unixmonkey]

That is very likely the problem. Try using just regular image_tag instead of wicked_pdf_image_tag.

[AdrienGiboire]

Any news regarding this issue? I can't use basic stylesheet_link_tag helper as it breaks the display.

EDIT: My bad. The error was issued because of a file missing in my manifest.

Hi there, I stay stuck on that issue for days, I really need help. Pdf conversion succeeds on local server but crash on heroku Here are my heroku logs:

I just encountered this same issue as well on Heroku, things work fine locally but the following error is thrown within my demo environment: ActionView::Template::Error: 403 Forbidden

Here is the backtrace

[krokrob]

My problem vanished with that config:

# Gemfile
gem 'wicked_pdf', github: 'mileszs/wicked_pdf'
gem 'wkhtmltopdf-binary'

# config/initializers/wicked.rb
WickedPdf.config = {}

<!-- page.pdf -->
<%= wicked_pdf_stylesheet_link_tag "application", media: 'all' %>

[ritec]

I was able to overcome my issue by limiting the amount of styles I was loading to the bare essentials for my pdf to render properly, leaving everything else I needed behind. I then started getting a similar issue with wicked_pdf_javascript_include_tag and again solved it by limiting JS to the bare essentials and loading everything I could from CDNs with the regular javascript_include_tag instead of using local files. Works for now.

[zerobatu]

We had the same problem and fixed changing:

<%= wicked_pdf_stylesheet_link_tag "documents-pdf" -%> for this <%= stylesheet_link_tag(wicked_pdf_asset_base64('documents-pdf')) -%>

[leom806]

Thanks @zerobatu, it helped me a lot. I would appreciate even more if you could say a little about why this alternative solved the problem, I guess it is about on how wicked_pdf request the resource but it is a guess though.
