DB Update Error: Isotope eCommerce Upgrade step "Version 2.3.0 stable" was not run successfully!

[JessesNei]

PHP 7.4 und 8.0
Contao 4.9.39 und Contao 4.13.16

I tried to update Isotope from 2.7.4 to 2.8.10 the update via Contao Manager works without any Problems.
But the Database Upate is not working.

I tried to update the Contao Core too and changed the PHP Version to 8.0 to check if it works than but i had alwas the same messsage.

In the Installtool i get the following message:

Isotope eCommerce Upgrade step "Version 2.3.0 stable" was not run successfully!
An exception occurred while executing a query: SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'FROM tl_iso_product WHERE IS NOT NULL' at line 2 in /home/httpd/vhosts/helialpin.ch/dev.helialpin.ch/vendor/doctrine/dbal/src/Driver/API/MySQL/ExceptionConverter.php on line 86

I guess this error happens because you have attributes that were not correctly configured and do not have a database field name. I have implemented a fix in ce6ce3d.
