Property 'authorId' does not exist on type 'Post[]'.

Coding along with the tutorial, and I came across this error I cant resolve. Portion in the video: 47:33 Code thus far:

import type { User } from "@clerk/nextjs/dist/api";
import { clerkClient } from "@clerk/nextjs/server";
import { z } from "zod";

import { createTRPCRouter, publicProcedure } from "~/server/api/trpc";

const filterUserForClient = (user: User) => {
  return {
    id: user.id, 
    username: user.username, 
    profileImageUrl: user.profileImageUrl}
}

export const postsRouter = createTRPCRouter({
  getAll: publicProcedure.query(async ({ ctx }) => {
    const posts = await ctx.prisma.post.findMany({
      take: 100,
    });

    const users = (
      await clerkClient.users.getUserList({
        userId: posts.map((post) => post.authorId),
        limit: 100,
      })
    ).map(filterUserForClient);


    console.log(users)

    return posts.map((post) => ({
      post,
      author: users.find((user) => user.id === posts.authorId),
    }));

    // return posts;
  }),
});

import type { User } from "@clerk/nextjs/dist/api";
import { clerkClient } from "@clerk/nextjs/server";
import { z } from "zod";

import { createTRPCRouter, publicProcedure } from "~/server/api/trpc";

const filterUserForClient = (user: User) => {
  return {
    id: user.id, 
    username: user.username, 
    profileImageUrl: user.profileImageUrl}
}

export const postsRouter = createTRPCRouter({
  getAll: publicProcedure.query(async ({ ctx }) => {
    const posts = await ctx.prisma.post.findMany({
      take: 100,
    });

    const users = (
      await clerkClient.users.getUserList({
        userId: posts.map((post) => post.authorId),
        limit: 100,
      })
    ).map(filterUserForClient);


    console.log(users)

    return posts.map((post) => ({
      post,
      author: users.find((user) => user.id === posts.authorId),
    }));

    // return posts;
  }),
});

can you send your prisma schema db pushing + restarting vs code will often fix a lot of weird type errors

You are trying to access .authorId on the whole array

^ I didnt even read the code but yes if you hover posts you can see, it doesnt have authorId, as it is an array
