Error deploying Rails 4.2 with Capistrano 3.4

I'm in the process of deploying my rails application to production and keep running into an TypeError: no implicit conversion of Array into String error. This is my first real deployment attempt, so I'm at a loss for where to start with debugging the error.

EBUG [634578b1] Finished in 0.179 seconds with exit status 0 (successful).
INFO [e1912f46] Running bundle exec rake assets:precompile as [email protected]
DEBUG [e1912f46] Command: cd /opt/www/testapp/releases/20150325215252 && ( RAILS_ENV=production bundle exec rake assets:precompile )

Does anyone have any experience with this error or have a good starting point for me to look?

It's failing in the assets:precompile step, you can try that yourself in your local machine by running:

bundle exec rake assets:precompile assets:clobber

If that gives you the same error then you know the issue isn't anything to do with Capistrano, but rather something to do with your assets. Maybe you can see where the problem is happening, or otherwise debug by looking though your app/assets/* files and seeing if there's something obvious to fix there.
