Al intentar implementar en Heroku, devuelve el siguiente error:

 ! The following is the full output from the installation attempt: ! ! > You are using Composer 1 which is deprecated. You should upgrade to Composer 2, see https://blog.packagist.com/deprecating-composer-1-support/ ! > Loading repositories with available runtimes and extensions ! > Updating dependencies ! > Your requirements could not be resolved to an installable set of packages. ! > ! > Problem 1 ! > - The requested package composer-plugin-api could not be found in any version, there may be a typo in the package name. ! >

No hay mucha información sobre cómo solucionar esto. ¿De qué otra manera debo especificar que se está utilizando el compositor 2? Todo fue instalado desde el compositor 2.
