JetStream $request->user() Null.

I'm trying to access backend route for get data from a external API inside a Livewire component method. But inside the Laravel Controller method i can not access $request->user() or auth()->user() if i already logged in. Thus the route is a public one both logged in and not logged in users can access that. the difference is auth user have different params and guest users has different params but same endpoint.

   public function loadPublications($params)
    {
        $page = $params['page'] ?? $this->currentPage;
        $language = $params['language'] ?? $this->selectedLanguage;
        $this->selectedLanguage = $language;
        $this->currentPage = $page;

        $response = Http::get(route('publications.get'), ['page' =>$this->currentPage, 'language' => $this->selectedLanguage]);

        if ($response->successful()) {
            $this->publications = $response->json();
        } else {
            // Handle the error
            $this->publications = [];
        }

      $this->dispatch('publications-loaded', ['pagination' => isset($this->publications['pagination']) ? 
      $this- >publications['pagination'] : null]);
    }

Route::get('/publications/get', [LarcierController::class, 'getPublications'])->name('publications.get');

public function getPublications(Request $request)
    {
        Log::info('Get Publications');
        $user = $request->user();
        $user2 = auth()->user();
}
