How to create an app on Heroku that copies another app's config vars and add-ons?

I've created review apps successfully, and the review apps do have all the correct config vars and add-ons copied, but I can't get the review apps to persist, or to move to 'staging' in the pipeline. They are automatically deleted when a pull request is closed.

When I create a new app in the pipeline under 'staging', I don't see any way to import the production app's config vars or add-ons.

The way this used to be done was via heroku fork, but that is now deprecated. I have tried using the heroku fork plug-in, but I run into installation problems:

$ heroku plugins:install heroku-fork
Installing heroku-fork@latest... ⣽
Installing heroku-fork@latest... !
 ▸    yarn add heroku-fork@latest --non-interactive
 ▸    --mutex=file:/Users/priyamurthy/.local/share/heroku/plugins/yarn.lock
 ▸    --preferred-cache-folder=/Users/priyamurthy/Library/Caches/heroku/yarn
 ▸    --registry=https://cli-npm.heroku.com exited with code 1
 ▸    error An unexpected error occurred:
 ▸    "https://cli-npm.heroku.com/heroku-fork: Hostname/IP does not match
 ▸    certificate's altnames: Host: cli-npm.heroku.com. is not in the cert's
 ▸    altnames: DNS:*.herokuapp.com, DNS:herokuapp.com".
 ▸
 ▸    yarn add v1.3.2
 ▸    [1/4] Resolving packages...
 ▸    info If you think this is a bug, please open a bug report with the
 ▸    information provided in
 ▸    "/Users/priyamurthy/.local/share/heroku/plugins/yarn-error.log".
 ▸    info Visit https://yarnpkg.com/en/docs/cli/add for documentation about
 ▸    this command.

How do people do this pretty basic task?

Don't know what is your use case but you can utilize Heroku Platform API during the build phase.

first you have to retrieve config vars from Staging:

GET https://api.heroku.com/apps/$STAGING_APP_ID_OR_NAME/config-vars

then update config vars on prod

PATCH https://api.heroku.com/apps/$PROD_APP_ID_OR_NAME/config-vars

Please refer to this page for more information https://devcenter.heroku.com/articles/platform-api-reference#config-vars

Do not use this approach during the release phase, each update on config vars will trigger a new release.
