Heroku "Couldn't find that app" in CI

Heroku could not resolve the app you named. The -a value or the git remote points at an app that does not exist, was renamed, or is not accessible to the authenticated account.

What this error means

A Heroku command fails with "Couldn't find that app." or git push reports the app does not exist.

 ▸    Couldn't find that app.

Common causes

Wrong or renamed app name

The -a app name or the heroku git remote URL does not match an existing app, so Heroku cannot find it.

The account cannot access the app

The app exists but the authenticated account is not a collaborator or owner, so Heroku reports it as not found.

How to fix it

Pass the correct app name

1. List apps with heroku apps to confirm the exact name.
2. Pass it with -a or set the heroku git remote correctly.
3. Confirm the account has access to the app.

heroku apps:info -a my-app

Set the git remote to the right app

Point the heroku remote at the actual app so git-push deploys target it.

heroku git:remote -a my-app

How to prevent it

• Confirm the app name with heroku apps.
• Keep the heroku git remote in sync with the app.
• Use an account that has access to the app.
