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",

first part from the Build Log:

I had faced a similar issue a year ago, I solved it by installing the node-sass in dependencies rather than dev dependency. It is/maybe a workaround, but it worked for me. — Zeeshan Nagori
