PDFKIT hangs while generating PDF in controller but not in console

I'm having issues while trying to generate PDFs using PDFKit. If issue the following commands on console:

kit = PDFKit.new("http://localhost:3000/invoices/57f0bf61fc7b3415fc000000")

followed by

kit.to_file("pdfs/invoices/57f0bf61fc7b3415fc000000.pdf")

Everything works fine and the file is generated. Now if I have the same code in a controller, the pdf generation hangs on step 1 and no error is displayed.

If I try wkhtmltopdf http://localhost:3000/invoices/ivoice_id invoice.pdf it also works.

Why is that? More importantly, how to fix it?

I'm using Rails 4.

Check https://github.com/pdfkit/pdfkit#troubleshooting

If you have some assets in that template that should be served by your local server, then in development in may hang depending on your server configuration. Your current request to render PDF "blocks" the server and it cannot respond to subsequent requests for assets (images, css, js). If possible, serve them from CDN, use multi-process server config in development etc.
