Cannot deploy to heroku

I am trying to use the 'Deploy to Heroku' button but after I add my app name and start deployment I am getting the following errors

@paxpelus Sorry about this, and thank you for opening this issue! This must be from recent PRs I merged from dependabot. I will fix this in the next few days and ping you here when it should be ready to deploy!
