Heroku automatically changing RAILS_ENV and RACK_ENV variables to "production" on every deploy

Question

Every time I push a new version to my staging heroku app, the RACK_ENV and RAILS_ENV variables are changed to "production", instead of "staging" which is the value I manually assigned. This started happening a couple of hours ago. A line like this is logged on the activity page on the heroku site on every deploy: v741 [email protected]: Add RAILS_ENV, RACK_ENV, PATH, LANG, GEM_PATH config 6 minutes ago

I should talk to heroku support, but it seems that now the only place where questions can be asked is here, they remove the site support...

Answer 1

Same here. Fortunately, it does not happen after a rollback.

Fortunately a deploy on production does not set the variables to staging !

EDIT:

Heroku answer on a ticket: Hi, looks like a bug on our end. I'm notifying our ruby team

EDIT 2:

They said the bug was fixed yesterday, and yes, it was. But… the bug has just happened again right now……
