When opening the product edit page in the backend, I get:
1 exception(s):
Exception #0 (Exception): Deprecated Functionality: Using null as an array offset is deprecated, use an empty string instead in /var/www/html/vendor/magento/module-catalog/Model/Entity/Product/Attribute/Design/Options/Container.php on line 31
Which comes from:
vendor/avstudnitz/scopehint2/Plugin/ProductEavDataProviderPlugin.php:74
I haven't investigated any further yet.
