Heroku is sending us emails to get us to upgrade to a newer stack.
Your recently built app codebar-production is using the Heroku-22 stack, which is deprecated.
From November 1st, 2026, the first build of each Heroku-22 app within a 30-day period will fail with a deprecation notice.
From February 1st, 2027, the frequency of these failures will increase to the first build of each app within a 7-day period.
From April 1st, 2027, the frequency of these failures will increase to the first build of each app per day.
On April 30th, 2027, Heroku-22 reaches end-of-life; apps using it will no longer receive security updates, and be run at your own risk.
From May 1st, 2027, builds will no longer be allowed for Heroku-22 apps.
Please upgrade to a newer stack as soon as possible.
See the Heroku-22 End-Of-Life FAQ for more details.
