CLI crashes when running in an nx monorepo

[ymc9]

Reportd by maxd on discord:

We tried upgrading and had some minor hurdles: we are used to running zenstack generate from within our ./libs/prisma folder of our nx monorepo, which also holds the schema.zmodel. When I try to generate from this directory it now throws an error:

⌛ ZenStack CLI v1.7.0, running plugins

An unexpected error occurred:

Moving to the root directory and running the command works correctly: yarn zenstack generate --schema libs/prisma/schema.zmodel
