No such entity error when saving product in single-store mode if website_id <> 1

[kyegil]

After upgrading to Magento 2.2.1 I'm no longer able to save products while the website is in single store mode. The website has previously had multiple store views.
I've been able to replicate the issue on a clean install of Magento 2.2.2
The problem is likely related to the fact that website_id != 1

Preconditions

• Magento version 2.2.1 or 2.2.2
• PHP version 7.0.22
• Mysql version 5.6.35
• Apache/2.2.32 (Unix)

Steps to reproduce

1. Install a clean version of Magento version 2.2.2
2. Add a new website, store and store view, and make this the default
3. Delete the preinstalled website, store and store view
4. Add a new product and save it
5. Change the configurations to single-store mode
6. Open the product and save it again

Expected result

1. The product should save successfully

Actual result

1. The save action fails, with the message 'No such entity.'

I had the same problem. When I disabled the single-store mode, I could save successfully.

This is the same error as I have ... But the single store mode makes no difference to me.

While waiting for a bug fix I solved this issue by making the following change to the core Product model (in the hope that this will be fixed by next time I update Magento):

In the Magento\Catalog\Model\Product::getStoreIds() method
(approx line 792 of vendor/magento/module-catalog/Model/Product.php):

Find
foreach ($websiteIds as $websiteId) {
Replace with
foreach ($websiteIds as $websiteId => $selected) {
