Vercel

Describe the Bug

I keep getting error once trying to build project with Vercel. It builds fine locally. Is there something i am overlooking? Only json file I have in repo is package.json

Running "vercel build"

15:22:31.883 | Vercel CLI 28.0.1
15:22:31.976 | Error! Can't parse json file

Expected Behavior

Congratulations built with success! ;)

Case sensitive imports / file names was an issue at then end. Exactly as in here:
#18176

Installing ESlint helped and so did not entering the env variables.

Just leaving it here in case someone is experiencing the same error. This is related to env variables. It doesn't work for me by inputing Google private key in the Vercel interface. Looks like im not alone.
