Configure multiple buildpacks

[Raphael Biersbach]

Hello guys,
First of all thanks for creating this awesome github action!
I am a bit new to this ecosystem so forgive me 🙇

I am currently using the action to deploy a discord bot to heroku: https://github.com/rbiersbach/discord-poll-bot
As I am using poetry I am using this buildpack to prepare the dependencies for the default python buildpack: https://github.com/moneymeets/python-poetry-buildpack
The documentation of the python-poetry-buildpack states that you usually would need to do something like this:

heroku buildpacks:clear
heroku buildpacks:add https://github.com/moneymeets/python-poetry-buildpack.git
heroku buildpacks:add heroku/python

As far as I understand you can only specify one buildpack in your github action, meaning I had to run heroku buildpacks:add heroku/python manually after deployment.

Is there a way to add a list of buildpacks or did I miss anything?

Thanks in advance!

Any news on that?

FYI we've walked around this by such approach:

• We configured Heroku to deploy specific app when pushed to branch
• We created GHA that pushes to branch. That way, the Heroku runs the deploy triggered by GHA action.
