This article serves as an addendum to the excellent article by Chris Fidao over on Laravel News.
When using Inertia, you may still want to serve some content without generating a session for an anonymous user.
# app/Http/Kernel.php
'static' => [
\Illuminate\Routing\Middleware\SubstituteBindings::class,
\App\Http\Middleware\HandleInertiaRequests::class,
],
However, if your Inertia middleware relies on any session data, stuff could blow up!

A quick fix is to return early in the share method of your HandleInertiaRequests
middleware.
public function share(Request $request)
{
if (!$request->hasSession()) {
return [];
}
// ... do the rest of your sharing stuff here.
}
That’s it! Happy developing!
