NestJS - Database with Prisma

You wrote this Prisma query in NestJS:

const posts = await prisma.post.findMany({ where: { title: 'Hello' } });

But you get a TypeScript error: Property 'title' does not exist on type 'PostWhereInput'.
What is the most likely cause?

AThe <code>title</code> field is missing in the Prisma schema for Post

BYou forgot to import PrismaClient

CThe database connection is not established

DYou used <code>findMany</code> instead of <code>findUnique</code>

Step-by-Step Solution

Solution:

Step 1: Analyze the TypeScript error
The error says title is not a valid filter field, meaning it is not defined in the Prisma schema for Post.
Step 2: Rule out other options
Missing import or connection issues cause different errors; findMany is valid here.
Final Answer:
The title field is missing in the Prisma schema for Post -> Option A
Quick Check:
Missing schema field = TypeScript error [OK]

Quick Trick: Check Prisma schema fields if TypeScript errors on filters [OK]
