    It looks like a conflict with the EventDispatcher library, as mentioned at https://stackoverflow.com/questions/67913020/typeerror-for-argument-2-in-solarium-client

    How can I resolve this? All we did was upgrading the plugin files which worked perfectly fine.

    If it is a conflict with Symfony\Component\EventDispatcher\EventDispatcher versions brought by other plugins, you could try to deactivate other plugins and see if the error disappears.
