undefined method `find_asset' for nil:NilClass in production with sprockets-rails 3.0.0

wicked_pdf_stylesheet_link_tag fails with NoMethodError: undefined method 'find_asset' for nil:NilClass in production with sprockets-rails 3.0.0

See here: rails/sprockets-rails#237

Something like this probably can be used instead of Rails.application.assets.find_asset:

manifest = Rails.application.assets_manifest
path = File.join(manifest.dir, manifest.assets['file.css'])
File.read(path)

I'm seeing the same thing with rails 4.2.5 and sprockets-rails 3.0.0.

And me. Same versions as leesmith.

I'm getting this same error on a Heroku instance. Any known versions where this doesn't happen?

@MaximilianoFelice Looks like any version of sprockets-rails less than 3.0 should work for now, but your issue may not be related. There's a number of reasons your asset might not be found.

@Bonias Would you be able to help test out that bit of code on a few different versions of Rails and send a PR?

[MaximilianoFelice]

@unixmonkey It seems to be the same issue described on the link provided by @Bonias, as turning assets.compile = true "fixes" it.

According to that link, by the way, sprockets team isn't very much willing to match the old behaviour any soon.

[aliyazdani]

rails 4.2, seeing the same issue in prod.
