Magento 2 – Can’t mass update attributes product/edit/action/inventory.phtml

When trying to mass update product attributes in Magento 2 admin, an empty page with just the store view option would appear and not the usual form.

Products could be updated individually but not in bulk.

Magento 2 system.log

The /var/log/system.log showed the following critical notice.

[2020-10-29 09:26:37] main.CRITICAL: Notice: Undefined offset: 32000 in /…/public_html/var/view_preprocessed/pub/static/vendor/magento/module-inventory-catalog-admin-ui/view/adminhtml/templates/catalog/product/edit/action/inventory.phtml on line 9

Can’t mass update attributes – Solution

A flaw in the Magento 1 to M2 migration script left out the setting for the minimum Quantity allowed in the shopping cart. The solution found in stackexchange is to update a config setting:

Stores -> Settings: Configuration -> Catalog -> Inventory -> Product Stock Options: Minimum Qty Allowed in Shopping Cart

Add the quantity ‘1’ for ‘ALL GROUPS’ and save.
