Can't clone heroku app

Question

I can't clone my heroku app (more than 2 years older) using the clone command because I get this error:

bamboo-mri-1.9.2 stack not supported

What I have to do?

Answer 1

SSH transport has been disabled in March 2022:

• https://devcenter.heroku.com/changelog-items/2215
• https://devcenter.heroku.com/changelog-items/2365

I had to download the code for an old project using slugs:

heroku plugins:install heroku-slugs
heroku slugs:download -a yourapp

Which produced an error:

Downloading... ████████████████████████▏  100% 00:00 564kB                                                                                                                                                                                   
tar: Error opening archive: Unrecognized archive format
 ▸    Command failed: tar -xf yourapp/slug.tar.gz -C yourapp
 ▸    tar: Error opening archive: Unrecognized archive format
 ▸  

So I installed squashfs as suggested here:

brew install squashfs
cd yourapp
unsquashfs -f -d out slug.tar.gz

Which will leave you with the code in the out directory.

Answer 2

You need to use ssh instead of https for the old stacks.

> heroku git:clone --ssh-git -a app

where app is the name of your heroku app
