Error compiling Rails 3 CSS asset on Heroku -

-

we're getting following error on random page loads:

error compiling css asset encoding::converternotfounderror: code converter not found (us-ascii utf-16be) (in /app/app/assets/stylesheets/master.css) /app/.bundle/gems/ruby/1.9.1/gems/sass-3.1.10/lib/sass/util.rb:494 in 'encode'

rails 3.1 app running on bamboo stack. i've never seen error locally.

if using rails 3.1 pipeline, need switch cedar.

from heroku documentation:

while rails 3.1 can run on bamboo stack without asset pipeline, rails 3.1 runs best on heroku’s cedar stack.

your error seems related encoding error in css file. suggest open file , check encoding utf-8.
