Production deployment Issues with large schemas (30+ models)
Hi Wasp team! 
I'm building a production SaaS on OpenSaaS and hit a critical blocker. My schema has grown to 32 models (733 lines) and
The issue: SDK generates stub types (20KB) instead of proper Prisma client (2.2MB), causing 88+ TypeScript errors.
Key finding: Development works perfectly with a workaround, suggesting it's specifically an SDK generation issue with large schemas.
I've submitted a detailed bug report here: https://github.com/wasp-lang/wasp/issues/3303
Critical question: Is 32 models beyond Wasp's intended scale? I'm at a decision point:
- Continue with Wasp (if fixable)
- Invest 3-4 weeks ejecting to Next.js/Express
Any guidance on timeline or whether this is solvable would be hugely appreciated!
Context:
- Wasp 0.18.0
- Node v24.3.0
- PostgreSQL (Neon)
- OpenSaaS template base
