I have used hugo server locally and the website builds without any issues. Same with hugo -D. Any help will be appreciated.
My repo can be seen here.

Thanks in advance!

PS: I see now that there is some third-party error on Netlify’s end regarding node installations.

PPS: Looks like it’s resolved now
