4. Enter that product names in a quck search on a magento frontend
5. Catch the 500 http issue

How to fix

Found the issue in vendor/emico/tweakwise/Model/Autocomplete/DataProviderHelper.php::getProductItems() line 147 The foreach loop should be like this

foreach ($response->getProductData() as $item) {
    $product = $productCollection->getItemById($item['id']);

     if (!$product) {
        continue;
    }

    $product->setData('tweakwise_price', $item['tweakwise_price']);

    $result[] = $this->productItemFactory->create(['product' => $product]);
}
Because a product can be null

$product = $productCollection->getItemById($item['id']);
$product->setData('tweakwise_price', $item['tweakwise_price']);
