Key Fixes

Null Handling Pattern

• For nullable JSON fields that can be null, use Prisma.JsonNull instead of null
• Pattern: value ? (value as Prisma.InputJsonValue) : Prisma.JsonNull

String vs JsonValue

• proofData fields should be string, not Prisma.InputJsonValue
• Pattern: proofData: proofData as string

Cleaner Type Casting

• Replaced as unknown as Record<string, unknown> with proper as Prisma.InputJsonValue
• This is cleaner and more type-safe

Progress

• Fixed additional ~15+ JsonValue errors in files we previously worked on
• Improved type safety by using proper Prisma types instead of workarounds
• Total JsonValue fixes so far: ~55+ instances across ~30 files
