Reactjs – Creating empty array initally as a field in prisma doesnt work

I am doing project with React Typescript Next and prisma, I am trying to create user with initally empty array as playlists field, I dont get any error but when i refresh my database (mongodb) i cannot see playlists prop on my newly created user. Firstly I thought that if that is empty I just cant see it, but then when i wanted to invoke to it and update this field, I realized that it is not possible.

My schema.prisma file:

model User {
  id             String   @id @default(auto()) @map("_id") @db.ObjectId
  name           String
  email          String   @unique
  emailVerified  DateTime
  image          String?
  hashedPassword String
  createdAt      DateTime @default(now())
  updatedAt      DateTime @updatedAt
  playlists      Playlist[]
  recentSearches Json[]
  liked          Json
}

model Playlist {
  id       String  @id @default(auto()) @map("_id") @db.ObjectId
  name     String
  tracks   Json[]
  image    String?
  isPublic Boolean @default(true)
  author   String?
  User     User    @relation(fields: [userId], references: [id])
  userId   String  @db.ObjectId
}

My register user logic:

export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse
) {
  if (req.method !== "POST") {
    return res.status(405).end();
  }
  try {
    const { email, name, password } = req.body;
    const existingUser = await prismadb.user.findUnique({ where: { email } });
    if (existingUser) {
      return res
        .status(422)
        .json({ error: "Email is already taken", cause: "email" });
    }

    const hashedPassword = await bcrypt.hash(password, 12);
    const user = await prismadb.user.create({
      data: {
        email,
        name,
        hashedPassword,
        image: "",
        emailVerified: new Date(),
        recentSearches: [],
        liked: {},
        playlists: { create: [] },
      },
    });

    return res.status(200).json(user);
  } catch (error) {
    console.log(error);
    return res.status(400).json(error);
  }
}

I tried using create and createMany attribute but nothing worked, I realized that if i use Json[] instead of Playlist[] it works but i want to have Playlists[] as a type.
I expect to create a user with empty array of playlists field in database.

The way i want then update my playlists field

const createdPlaylist = await prismadb.playlist.create({
      data: { name: playlistName, tracks: [], userId: user.id },
    });
    
const result = await prismadb.user.update({
    where: { id: user.id },
    data: { playlists: { connect: { id: createdPlaylist.id } } },
});
