Missing Amasty\SeoToolkitLite\Model\Source\Eav\Robots class

Missing Amasty\SeoToolkitLite\Model\Source\Eav\Robots class

I've installed amasty/module-seo-toolkit v2.1.2 package which requires amasty/module-seo-toolkit-lite 1.1.0 or higher. The newest version of module-seo-toolkit-lite I have access to is 1.1.4 and this one was installed.

The problem:

Amasty\SeoToolkitLite\Setup\Patch\Data\AddCanonical install amtoolkit_robots attribute and set its source to non existing class Amasty\SeoToolkitLite\Model\Source\Eav\Robots
