SvelteKit PageLoad module not found

Issue

I have a SvelteKit project and for some reason, ./$types doesn't have the module PageLoad (which other projects do. I'm not sure what I did/didn't do to not have it. This is the error I'm getting:

Module '"./$types"' has no exported member 'PageLoad'.ts(2305)

This is how I'm using it (for testing):

import { error } from '@sveltejs/kit';
import type { PageLoad } from './$types';

export const load: PageLoad = async ({ params, fetch }) => {
  console.log('props from +page.ts: ', params.db_item)
  // We fetch the post here using a Worker/Lambda
  return params.db_item
}

Here is my package.json file:

{
    "name": "test",
    "version": "0.0.1",
    "private": true,
    "scripts": {
        "dev": "vite dev",
        "build": "vite build",
        "preview": "vite preview",
        "test": "playwright test",

    },
    "devDependencies": {

    },
    "type": "module",
    "dependencies": {
        "svelte-share-buttons-component": "^1.5.0"
    }
}

Here is my svelte.config file:

import adapter from '@sveltejs/adapter-cloudflare';
import preprocess from 'svelte-preprocess';

/** @type {import('@sveltejs/kit').Config} */
const config = {
    // Consult https://github.com/sveltejs/svelte-preprocess
    // for more information about preprocessors
    preprocess: preprocess(),

    kit: {
        adapter: adapter()
    }
};

export default config;

Let me know if there's anything else I should provide. Thanks!

Solution

This is absolutely crazy, but I figured it out.

I had initially named the file +page.js and renamed it to .ts. Apparently, that throws everything off. After deleting the file and creating it with .ts extension, the $types import worked perfectly. Nowhere does it say anything in the documentation, but that's what it was.
