node -v
v13.6.0

after executing "$ USER=schlos REPO=foie-graphs TOKEN=OAUTH_GUTHUB_token ALAVETELI=http://imamopravoznati.org npm start" I got error:

Do you have an idea what could be the problem? NPM version?
It worked until now each year, only change this year is that I have fresh OS and fresh homebrew and fresh NPM install.

Thanks!
