"id.endsWith is not a function" ERROR after fresh installation of laravel using vite and inertia.js

When you encounter the error message "id.endsWith is not a function" after a fresh installation of Laravel using Vite and Inertia.js, it's likely due to a misconfiguration or missing dependency. Here's a step-by-step guide to help you troubleshoot and resolve this issue.

Check your JavaScript dependencies:

First, ensure that you have installed all the required JavaScript dependencies for Laravel, Vite, and Inertia.js. You can install them using npm or yarn by running the following command in your terminal:

npm install laravel-vite-plugin filament inertia inertia-react laravel-jwt-auth

yarn add laravel-vite-plugin filament inertia inertia-react laravel-jwt-auth

Configure Laravel Vite Plugin:

Next, configure the Laravel Vite Plugin by adding the following lines to your webpack.mix.js file:

require('laravel-vite-plugin')
  .vue()
  .react()
  .inertia()
  .provide('window', { document: window.document });

Configure Inertia.js:

Make sure you have properly configured Inertia.js in your app/Providers/AppServiceProvider.php file by adding the following lines:

use Inertia\Inertia;
use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return Inertia::render('Welcome', [
        'canLogin' => Auth::check(),
        'canAdmin' => false,
    ]);
});

Create a new Inertia.js component:

Create a new Inertia.js component in the resources/js/Pages directory, for example, Welcome.js. Add the following code to the file:

import { InertiaApplication, Link } from '@inertiajs/inertia-react';
import { Head } from '@inertiajs/inertia';

export default function Welcome({ canLogin, canAdmin }) {
    return (
        <InertiaApplication
            initialPage={ '/' }
            resolveComponent={(name) => require(`./Pages/${name}`).default}
        >
            <Head title="Welcome" />

            <div className="w-full h-screen flex items-center justify-center">
                <div className="bg-white p-6 rounded-lg shadow-md w-full max-w-sm">
                    <h1 className="mb-4 text-xl font-medium text-gray-900">
                        Welcome to Laravel!
                    </h1>
                    <p className="text-sm text-gray-600">
                        {canLogin ? 'You are logged in.' : 'Please log in.'}
                    </p>

                    {canLogin ? (
                        <Link
                            href="/admin"
                            as="/admin"
                            className="block mt-4 text-sm text-gray-900 underline"
                        >
                            Go to admin panel
                        </Link>
                    ) : null}
                </div>
            </div>
        </InertiaApplication>
    );
}

Update your routes/web.php file:

Update your routes/web.php file to use Inertia.js routes:

use Inertia\Inertia;

Route::get('/', function () {
    return Inertia::render('Welcome');
});

Route::middleware([
    'auth:sanctum',
])->group(function () {
    Route::get('/dashboard', function () {
        return Inertia::render('Dashboard');
    });

    // Add your admin routes here
});

Check for typos:

Make sure there are no typos in your code, especially when importing or using functions like endsWith. Double-check your file and folder names, as well as your imports.

Clear your cache:

Clear your Laravel cache by running the following command in your terminal:

php artisan cache:clear

Verify and compile your assets:

Finally, verify and compile your assets using Vite:

npm run dev

yarn dev

Now, try accessing your application again and see if the "id.endsWith is not a function" error is resolved. If you still encounter issues, please let us know in the comments, and we'll help you further.
