Prisma Types

Pls somebody help with these types

type PostFindUniqueResult = Prisma.Result<
  typeof db.post,
  {
    where: {
      id: string;
    };
    include: {
      author: true;
      tags: true;
      comments: {
        include: {
          author: true;
        };
      };
    };
  },
  'findUnique'
>;

  let post: PostFindUniqueResult;
  
    post = await PostModel.findUnique({
      where: {
        id: params.id,
      },
      include: {
        author: true,
        tags: true,
        comments: {
          include: {
            author: true,
          },
        },
      },
    });

type PostFindUniqueResult = Prisma.Result<
  typeof db.post,
  {
    where: {
      id: string;
    };
    include: {
      author: true;
      tags: true;
      comments: {
        include: {
          author: true;
        };
      };
    };
  },
  'findUnique'
>;

  let post: PostFindUniqueResult;
  
    post = await PostModel.findUnique({
      where: {
        id: params.id,
      },
      include: {
        author: true,
        tags: true,
        comments: {
          include: {
            author: true,
          },
        },
      },
    });

I am getting error that the type PostFindUniqueResult is not the same as the return type from PostModel.findUnique

same as this one and so on

  type PostFindManyResult = Prisma.Result<
  typeof db.post,
  {
    include: {
      tags: {
        select: {
          name: true,
        },
      },
    },
  },
  'findMany'
>;

  const posts:PostFindManyResult = await PostModel.findMany({
    include: {
      tags: {
        select: {
          name: true,
        },
      },
    },
  });

  type PostFindManyResult = Prisma.Result<
  typeof db.post,
  {
    include: {
      tags: {
        select: {
          name: true,
        },
      },
    },
  },
  'findMany'
>;

  const posts:PostFindManyResult = await PostModel.findMany({
    include: {
      tags: {
        select: {
          name: true,
        },
      },
    },
  });

PostFindUniqueResult is the correct type, but PostModel.findMany doesnt return it PostModel.findMany return only Post[] instead of Post[] & Tag: {name: string}

hello. try it like this

const postWithUser = Prisma.validator<Prisma.PostDefaultArgs>()({
    include: {
        User: true
    }
});
export type PostWithUser = Prisma.PostGetPayload<typeof postWithUser>;

const postWithUser = Prisma.validator<Prisma.PostDefaultArgs>()({
    include: {
        User: true
    }
});
export type PostWithUser = Prisma.PostGetPayload<typeof postWithUser>;
