Error when adding a product in cart

LilD

Hi, I've changed the grouped products a bit so that I want only the product grouped with its data and price in my cart.
The product is added to the cart but the price is always 0 and from my debut it appears instead that the price is 0 when the cart takes over the items but when I send this item it has a price
Look how I did it

$productFlat = ProductFlat::where('product_id', $data['product_id'])->first();

        $productTest = Product::findOrFail($productFlat->product_id);

        $products = [
            [
                'product_id'        => $productFlat->product_id,
                'sku'               => $productFlat->sku,
                'quantity'          => $data['quantity'],
                'name'              => $productFlat->name,
                'price'             => $productFlat->price * $data['quantity'],
                'base_price'        => $productFlat->price * $data['quantity'],
                'total'             => $productFlat->price * $data['quantity'],
                'base_total'        => $productFlat->price * $data['quantity'] * $data['quantity'],
                'weight'            => $productFlat->weight ?? 0,
                'total_weight'      => ($productFlat->weight ?? 0) * $data['quantity'],
                'base_total_weight' => ($productFlat->weight ?? 0) * $data['quantity'],
                'type'              => $productFlat->type,
                'additional'        => $this->getAdditionalOptions($data),
            ],
        ];

        return $products;
