问题描述:

I am just having an issue to push my changes after I followed steps to upgrade my heroku instance from cedar-10 to cedar-14. Although it works if I create new app and apply existing code, it doesn't work to on production app.

Error

Any idea what it can be ?

网友答案:

Heroku support told me:

This is not exactly a bug, moving between cedar-10 and cedar-14 is an entire operating system upgrade and creating a disk image with completely parity is nearly impossible. You can purge the build cache on your own with the repo:purge_cache command via heroku-repo plugin.

Following those steps worked for me:

$ heroku plugins:install heroku-repo
$ heroku repo:purge_cache 
网友答案:

I ended up opening a ticket directly through support on Heroku platform.

Obviously, it was a bug on their side. So, an Engineer from Heroku needed to purge build cache for my application. After that action, I was able to push new changes and deploy new release.
