I simply tried to follow the Heroku guide to create a simple laravel app (even without db connection) and deploy on a Heroku app. However, it appears that when using Composer 2 there are problems (see log here). Rolling back to Composer 1 is all right. In the Heroku documentation it is indicated that Composer 2 is supported but obviously I am doing something wrong since it gives me an error.
when I push modifications to Heroku i get this error:
