React app deployment fails on digitalocean app platform.

So i am trying to deploy my MERN app to digitalocean app platform, both backend and frontend(react) part.

the backend part builds and deploys successfully, but the frontend part builds successfully but fails at deployment.

here are the frontend deployment logs:
