I have created a simple React application that works locally, but for some reason, Heroku keeps giving me this error message when I try to deploy it. I have been googling for solutions and trying everything I can find, but this error still persists. I am still a beginner in this, and would gladly appreciate any help or advice. If anyone would like to try it, my repository which I am trying to deploy from is https://github.com/shittake/findabudbud. Thank you in advance.
