False alarm. It was my environment. npm cache clean --force did the trick. Closing.

Yeah, sorry, didn't look into your issue earlier, as it had no repro and npm wouldn't even allow publishing a package with broken package.json, so assumed it was on your end until proven otherwise :)

I had the same issue.. npm cach clean --force wasn't working for me. So i deleted node modules folder ran npm i once again.. and boom, it worked!

For anyone else having the same issues. :)
