Next.js + ZenStack Auth Context Error Fix

Problem

In Next.js production builds, manually creating ZenStack auth contexts with db.$setAuth() can cause type mismatches that manifest as generic Server Components render errors. The actual error details are hidden in production for security, making debugging extremely difficult.

Context / Trigger Conditions

When this occurs:

• Next.js app in production shows generic error page
• Sentry/error tracking shows: "An error occurred in the Server Components render. The specific message is omitted in production builds to avoid leaking sensitive details."
• Same code works perfectly in development environment
• Using ZenStack ORM with Better Auth
• Using Server Components or Server Actions with database queries
