Product is not found

Error message

Product is not found

What it means

Thrown in PrepareShoppingCartItemListModelAsync (admin shopping-cart search) when searchModel.ProductId > 0 (isSearchProduct) but _productService.GetProductByIdAsync returns null. The search was filtered by a product that does not exist, so the factory cannot resolve product context for the grid and throws a bare Exception. It indicates a stale product id in the search filter.

Solutions

Clear the ProductId filter or pick a valid product from the autocomplete.
Verify the ProductId still exists (not Deleted) before submitting the search.
Guard the search model: if ProductId > 0 but the product is missing, show a friendly message and return an empty grid instead of throwing.
Refresh any cached/deep-linked search URLs.

Example fix

// before
if (isSearchProduct)
{
    product = await _productService.GetProductByIdAsync(searchModel.ProductId)
        ?? throw new Exception("Product is not found");
}
// after (graceful handling)
if (isSearchProduct)
{
    product = await _productService.GetProductByIdAsync(searchModel.ProductId);
    if (product is null)
    {
        _notificationService.WarningNotification("The selected product no longer exists.");
        product = null;
    }
}

Defensive patterns

Strategy: validation

Validate before calling

// Validate the search product id before building the cart grid.
if (searchModel.ProductId > 0)
{
    var product = await _productService.GetProductByIdAsync(searchModel.ProductId);
    if (product is null)
    {
        _notificationService.WarningNotification("Selected product no longer exists.");
        searchModel.ProductId = 0; // fall back to unfiltered search
    }
}

Type guard

static bool ProductExists(Product p) => p is not null;

Try / catch

try { /* PrepareShoppingCartItemListModelAsync body */ }
catch (Exception ex) when (ex.Message == "Product is not found")
{
    _notificationService.WarningNotification(ex.Message);
    /* return empty grid */
}

Prevention

Avoid deep-linking cart searches with a fixed product id.
Validate productId > 0 and resolvable before submitting the search.
Clear stale product filters when products are deleted.

When it happens

Trigger: Admin opens the shopping cart/wishlist search grid and enters/links a ProductId that no longer exists (deleted or never created), and isSearchProduct evaluates true. The lookup returns null and the exception fires.

Common situations: Following a deep link with a product id that was deleted; product id passed from an external tool/report that is out of date; multi-store where the product is not in scope; copy-paste of a wrong id into the product filter.
