I am using Prisma with nestjs and having a problem seeding to PostgreSQL DB, when I run seed command I get that the seed is done but the db isn't affected, nothing else is logged out

What’s present in your seed script?

this and seems like it's not executed at all

import { PrismaClient, Prisma } from '@prisma/client';

const prisma = new PrismaClient();

const userData: Prisma.UserCreateInput[] = [
  {
    name: 'Alice',
    email: '<mailto:alice@prisma.com|alice@prisma.com>',
  },
  {
    name: 'Nilu',
    email: '<mailto:nilu@prisma.com|nilu@prisma.com>',
  },
  {
    name: 'Mahmoud',
    email: '<mailto:mahmoud@prisma.com|mahmoud@prisma.com>',
  },
];

async function main() {
  console.log(`Start seeding ...`);
  for (const u of userData) {
    const user = await prisma.user.create({
      data: u,
    });
    console.log(`Created user with id: ${user.id}`);
  }
  console.log(`Seeding finished.`);
  console.log(await prisma.user.findMany({}));
}

main()
  .catch((e) => {
    console.error(e);
    process.exit(1);
  })
  .finally(async () => {
    await prisma.$disconnect();
  });

What’s the name of the file and how are you running it?

seed.ts and im running it using

yarn prisma db seed --preview-feature

@janpio any idea here? The script sees fine though.

This looks like Windows, and the current version of seeding has never worked on Windows - there is an issue about that.

Thanks @janpio
