Suddenly stopped working today. Any idea why?

This might be related to lovell/sharp#186. If so, it seems that v0.20.0+ will have a 'prebuild' that could resolve your issue.

Also, I have noted that this is an intermittent issue. Which to me means that a new commit or an empty commit like below may clear up the issue. I prefer upgrading and see if that solves it ;)

git commit --allow-empty -m "force Heroku rebuild"
git push heroku master

UPDATE: updating package.json to use [email protected] (the latest as of today) did not resolve the intermittent issue with my Heroku instance. Note I am not using heroku-buildpack-vips, I just thought this discussion might be relevant/helpful to this thread. Sorry I don't have better news.
