Using API route in inertia with laravel always returns unauthenticated

On my HTTP Kernel I've added the class EnsureFrontendRequestsAreStateful so it can take care of the sessions

'api' => [
            \Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
            \Illuminate\Routing\Middleware\ThrottleRequests::class . ':api',
            \Illuminate\Routing\Middleware\SubstituteBindings::class,
        ],

On my vue component I've also tried to use axios and router from inertia, but both solutions ended up giving me the error:

"Attempt to read property "storeCredential" on null"

Using router from inertia

router.get(`/api/store/${storeSku.value}`, {
    preserveState: true,
    onStart: () => set(isLoadingAddProduct, true),
    onSuccess: (page) => {
      console.log('Sucesso!', page)
    },
    onError: e => {
      console.log('Erro!', e)
    },
    onFinish: () => set(isLoadingAddProduct, false),
  })

Using axios

axios.get(`/api/store/${storeSku.value}`)
    .then(res => {
      set(errors, { storeSku: '' })
      set(selectedProductFromStore, res.data)
    })
    .catch(error => {
      if (error.response.status === 404) {
        set(selectedProductFromStore, {})
        set(errors, { storeSku: error.response.data.message })
      }
    })
    .finally(() => set(isLoadingAddProduct, false))

My route

Route::prefix('store')->group(function () {
    Route::get('/{sku}', [StoreProductController::class, 'show'])->name('store.index');
})->middleware(['auth:sanctum']);

The controller method

public function show(string $sku, Request $request): JsonResponse
    {
        $product = FindProductOnUserStore::run($request->user()->storeCredential, $sku);

        abort_unless($product, 404, 'Não foi possível encontrar o produto');

        return response()->json($product);
    }

What else can I do to call the "api" route from my components?
