Key Patterns Applied

Empty Object Casting

• {} → {} as Prisma.InputJsonValue for empty objects assigned to JsonValue fields

Null Handling for Optional JsonValue

• value || null → value ? (value as Prisma.InputJsonValue) : Prisma.JsonNull
• This ensures proper type compatibility for nullable JsonValue fields
