FATA[0000] unrecognized image format

[cmoulliard]

I can build a project using docker but not at all when I execute the equivalent nerdctl build command within the same project

git clone https://github.com/halkyonio/my-backstage.git
cd my-backstage
yarn install; yarn build
cd packages/backend
docker build -f Dockerfile --tag backstage ../..
