database error

-- url of the page with the problem -- : yumas6.sg-host.com/
-- HikaShop version -- : HikaShop Business 4.6.1 [2207201754]
-- Joomla version -- : 4.2.6
-- PHP version -- : 7.4.33
-- Error-message(debug-mod must be tuned on) -- : Database not set in Joomla\CMS\Form\Field\TagField

Can someone help me resolve this error?
It seems to have occurred after importing products from another site.
Once I go into Hikashop and click on products, then click on any product, this occurs.
