Heroku deploy fails because of moontoast math and Nova

I have a laravel 8 application that is also using Nova. I would like to deploy to Heroku. When heroku tries to build I get the follow error about using to man PHP versions ?

Has anyone run into a similar issue and if so, how should I solve this?
