Heroku pipeline drops buildpack settings for Review Apps

Question

I'm currently using Heroku Pipeline feature for automatically detecting, building and deploying pull requests for review.

✓ Create new review apps for new pull requests automatically

URL pattern Pattern: Random pipeline-xxxxxx-xxxxxx.herokuapp.com

The problem is that my app needs a combination of 2 buildpacks in a specific order in order to boot properly.

The main/production app has this settings and it works fine(e.g. after each time a PR is merged).

From what I see Review Apps doesn't have a concept of buildpack settings and it tries to autodetect it each time.

What I've tried:

Open the latest Review App, set buildpacks, rebuild or push a new commit. It works fine in that Pull Request/branch/Review App but for each new PR this process has to be repeated manually.

Is there any way to overcome this issue?

In case you have a similar issue, one approach that you can use(that worked for me)

app.json Heroku's convention file where you can list your buildpacks among many other settings.

Could you please post a working app.json? I'm trying to set this up but Heroku appears to be ignoring my app.json file – Alex Launi Apr 15 '21 at 15:56
Hi, I am facing the same problem. setting buildpacks to app.json worked once but new review apps are still failing – Deepak Mahakale Sep 21 '21 at 15:47
