heroku push suddenly failing

问题

I pushed out to heroku last night, and now today my pushes are failing with the following error. Heroku status appears to be ok. My heroku config has RAILS_MASTER_KEY set to my master.key. That did not help.

Any experience this...or, able to point me towards a fix?

Command: 'bin/rails runner "puts %Q{heroku_detecting_active_storage_config=#{Rails.application.config.active_storage.service}}"' failed unexpectedly:
remote:  !     Missing encryption key to decrypt file with. Ask your team for your master key and write it to /tmp/build_996b65d7dc5d21b59fdaad7cc82a7aba/config/master.key 
               or put it in the ENV['RAILS_MASTER_KEY'].
