Issue with Index Route After Deploying Laravel 10 + Vue 3 SPA to VPS

Hi there,

I'm currently working on an SPA project using Laravel 10, Vue 3, and Vite. Everything worked perfectly in my local environment, but after deploying the project to my VPS with Plesk, I'm encountering some issues.

The problem is specifically with the index route:

When I access the domain directly (e.g., mydomain.com), I get a 500 error, but there are no detailed error messages. However, when I access other routes like mydomain.com/login, everything works just fine. Here’s my current setup:

public\index.php

<?php

use Illuminate\Contracts\Http\Kernel;
use Illuminate\Http\Request;

define('LARAVEL_START', microtime(true));

/*
|--------------------------------------------------------------------------
| Check If The Application Is Under Maintenance
|--------------------------------------------------------------------------
|
| If the application is in maintenance / demo mode via the "down" command
| we will load this file so that any pre-rendered content can be shown
| instead of starting the framework, which could cause an exception.
|
*/

if (file_exists($maintenance = __DIR__.'/../storage/framework/maintenance.php')) {
    require $maintenance;
}

/*
|--------------------------------------------------------------------------
| Register The Auto Loader
|--------------------------------------------------------------------------
|
| Composer provides a convenient, automatically generated class loader for
| this application. We just need to utilize it! We'll simply require it
| into the script here so we don't need to manually load our classes.
|
*/

require __DIR__.'/../vendor/autoload.php';

/*
|--------------------------------------------------------------------------
| Run The Application
|--------------------------------------------------------------------------
|
| Once we have the application, we can handle the incoming request using
| the application's HTTP kernel. Then, we will send the response back
| to this client's browser, allowing them to enjoy our application.
|
*/

$app = require_once __DIR__.'/../bootstrap/app.php';

$kernel = $app->make(Kernel::class);

$response = $kernel->handle(
    $request = Request::capture()
)->send();

$kernel->terminate($request, $response);

public.htaccess

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews -Indexes
    </IfModule>

    RewriteEngine On

    # Handle Authorization Header
    RewriteCond %{HTTP:Authorization} .
    RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    # Redirect Trailing Slashes If Not A Folder...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_URI} (.+)/$
    RewriteRule ^ %1 [L,R=301]

    # Send Requests To Front Controller...
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]
</IfModule>

routes\web.php

<?php

use Illuminate\Support\Facades\Route;

/*
|--------------------------------------------------------------------------

|

| routes are loaded by the RouteServiceProvider and all of them will
| be assigned to the "web" middleware group. Make something great!
|
*/

Route::get('{any?}', function () {
    return view('app');
})->where('any', '.*');

Does anyone have any ideas on what could be causing this issue?

Thank you!
