npx zenstack generate doesn't work, maximum call stack errors.

[daveycodez]

I tried to add ZenStack to my existing NextJS project. It's brand new with create-next-app@latest.

All I do is run these 2 commands and it fails.

npx zenstack@latest init

I'm on macOS if that matters.

I did some research and it might be a specific issue with ARM based Macs.

lovell/sharp#3944

Someone had this error only on an arm Mac with Sharp

HI @daveycodez , could you help check the versions of "langium" and "chevrotain*" in your project? I suspect it's due to a version mismatch.

npm ls langium
npm ls -a | grep chevrotain

[daveycodez]

npm ls langium
npm ls -a | grep chevrotain

Thanks for sharing this. It seems there're two versions of chevrotain installed, but I couldn't reproduce the issue locally after installing both. Do you have a sharable repro project?
