$page variable cannot be found about inertia-laravel

[Arturexe]

Welp, here I am having no idea what's happening and no useful answer anywhere.

How did you fix it?

This "Undefined variable $page" error might happen, if your routing doesn't respond with an inertia response.

You can respond within a controller as shown in https://inertiajs.com/responses#creating-responses.

// routes/web.php
Route::get('/demo', [DemoController::class, 'show']);

<?php

namespace App\Http\Controllers;

use Inertia\Inertia;
use Inertia\Response;

class DemoController extends Controller
{
    public function show(): Response
    {
        return Inertia::render('Demo', [
            'demodata' => 'foobar',
        ]);
    }
}

---

Or you can shortcut the routing as mentioned at https://inertiajs.com/routing#route-helpers:

// routes/web.php
Route::inertia('/demo', 'Demo');

Just after submitting this issue I figured it out.
Sorry. Closing

What worked for me was switching from view('app') to inertia('app')

For newbies like me getting this error, I tried migrating from a Livewire app to an Inertiajs app and this was a stumbling block. On this page it's spelt out:

By default the Laravel adapter will use the app.blade.php view. This template should include your assets, as well as the @inertia directive. If you'd like to use a different root view, you can change it using Inertia::setRootView().

I was able to clear this error just by running php artisan optimize:clear. Turned out there was an old "{any}" route still cached from before Breeze overwrote it.

@kapsonic or @msslgomez, did you resolve the issue? Can you explain it?

[Juhlinus]

@smbdelse What does you resources/views/app.blade.php file look like?

Make sure that it resembles this:

https://github.com/inertiajs/pingcrm/blob/master/resources/views/app.blade.php

Note the @inertia blade helper.

Blade file was ok, it ended up to be a stupid problem with a controller (just a typo). Thanks anyway! :)
