Automatic SKU generation issue

[samuelabate]

Hello there,

I was using this great library but I encountered an issue. I am on Laravel 5.7 and even though I have created the inventory with category_id and metric_id provided, the sku is not generated. The functions $inventory->generateSku(), $inventory->regenerateSku() and $inventory->hasSku() all return an empty string even though $inventory->createSKU("skuCode"); works fine. If you need to know, Here is the code i've used:

        try {

            $inventory = new Inventory();

            $inventory->name = $request->inventoryName;
            $inventory->category_id = $request->categoryId;
            $inventory->metric_id = $request->metricId;
            $inventory->description = $request->inventoryDescription;

            $inventory->save();

            $inventory->category;
            $inventory->metric;
            $inventory->sku;

            $response['success'] = true;
            $response['inventory'] = $inventory;
            $response['message'] = "Inventory Created Successfully.";
        } catch (\Exception $e) {
            $response['success'] = false;
            $response['message'] = $e->getMessage();
        }

Can you please suggest what I should do to resolve the issue?
