If I try to search a host or hostgroup by a paramter like:

has params.myparameter

This gives me in the hosts section the following error:

undefined method `table_name' for nil:NilClass

and in the host group search the following error:

Invalid search query: Field 'params.myparam' not recognized for searching!

We are running foreman version 1.24.2.

If you need any further information, just let me know.
