Could you include more details? A minimal reproduction snippet would be appreciated.

I’ve successfully diagnosed the issue. A direct Zod schema was unexpectedly passed as a parameter via the controller’s method handler. Interestingly, the linting process was bypassed when the schema was substituted for the type.
