Facet link giving error when added as a reference field in layout builder

It looks like this is a module incompatibility problem. You're using a module called hook_event_dispatcher which overrides a service that ERFL expects. Try uninstalling the other module and see if that fixes the problem. If it works, then I will look into patching ERFL to fix the problem.

Actually, that error message doesn't make any sense. There is no argument 10 to EntityReferenceFacetFormatterBase::__construct(). There's no $module_handler variable in the entire module. Line 87 is a closing parenthesis and line 110 is a comment. Did you hack the code?

There was no further response. I'm going to assume this was a bug caused by hacking the code. Feel free to reopen it if I'm incorrect.
