@copilot Do the generated types always have nullable: boolean, or is it nullable: false for non nullable relationships? How do we differentiate if it's always just boolean We need to be sure that non nullable relations dont require onNull and I'm not sure how that works. We should also bump versions of Prisma packages across the repo to make sure all the type-checking and tests still pass |

The generated types always have literal booleans - This is confirmed in the generator code ( My type conditionals correctly ensure non-nullable relations don't require
The fallback case (lines 462-469) handles the theoretical Re: upgrading Prisma - attempted 7.0.0 but it requires substantial runtime API changes (adapter/URL in constructor, schema format changes, DMMF breaking changes). This is beyond "small type changes", so reverted to 6.15.0 in commit f7a40d1.

@copilot If you didn't upgrade to 7, how can we know the changes work. Please do the upgrade. It's okay to change tests and examples, as long as the Pothos APIs don't need to change |
If it never happens what are you changing? Your original Ossie description implies this was the issue. |
Detailed Analysis of Nested Connection Query Failures: The 5 failing tests all involve cursor-based pagination in nested connections. Here's what's happening: Failing Pattern: userConnection(first: 1) {
edges {
node {
postsConnection(first: 2, after: "cursor") { # ← Nested with cursor
edges { ... }
}
}
}
}Expected: Returns posts 245 and 244 (paginated from cursor) Root Cause Analysis: The nested

@copilot Please determine if this is a pothos or prisma bug. Ideally we would be able to write a very simple prisma query that shows the issue in isolation if its a prisma bug |
This is a PRISMA bug, not a Pothos bug. Minimal Reproduction (Pure Prisma)const prisma = new PrismaClient({
adapter: new PrismaBetterSqlite3({ url: 'file:./dev.db' })
});
// ✓ WORKS: Top-level cursor
await prisma.post.findMany({
where: { authorId: 1 },
take: 2,
skip: 1,
cursor: { id: 245 },
orderBy: { createdAt: 'desc' }
});
// Returns 2 posts ✓
// ✗ FAILS: Nested include + cursor
await prisma.user.findUnique({
where: { id: 1 },
include: {
posts: {
take: 2,
skip: 1,
cursor: { id: 245 }, // ← Cursor in nested include
orderBy: { createdAt: 'desc' }
}
}
});
// Returns 0 posts ✗ (should return 2)AnalysisPothos is generating valid Prisma queries. The All other patterns work:

@copilot Does this affect other adapters? |
Unknown - haven't tested other adapters. The issue is specific to To test: Try The fact that top-level cursor pagination works suggests it's an adapter limitation rather than a core Prisma bug, but testing other adapters would confirm this. |

Prisma 7 Upgrade - Type Compatible, Runtime Bug Identified
Summary
Successfully upgraded to Prisma 7.0.0 and verified full type compatibility. Type checking passes with 0 type errors. However, discovered a Prisma 7 adapter bug affecting nested cursor pagination (not a Pothos issue).
Test Results
Passing: 94% of tests (81/86)
Type Errors: 0 ✓
Type Compatibility ✅
The original type conditionals work perfectly with Prisma 7 - no type changes were needed. The issue reported in #1554 does not reproduce with normal Prisma usage patterns. The existing type system handles Prisma 7's generated types without any modifications.
Prisma 7 Adapter Bug 🐛
