Heroku react app build failed (node-sass)

Question

• the last build was working and only UI changes in this build.
• I only changed the device I'm working with, so maybe I forgot to download something.
• I don't know why this isn't working.
• I failed to solve this problem in anyway.

"node-sass": "^5.0.0",
