I dont know what to do. 
pnpm --filter game-web build (fails because Corepack cannot download pnpm through the proxy tunnel). see and understand the problem! →
Can you explain more about the error you’re getting with corepack?
github repo using vercel i get blocked by a proxy trying pnpm
for me, somehow i had to make a proxy of 8000 for it to work. actually just using yarn now but pnpm tested good on the proxy, oh btw i am using codex to write the code and then its updated to github which i can run on vercel. I am a newbie but this was a hell of a test for me
