[BUG] A `object_id_field` will throw `class java.util.ArrayList cannot be cast to class java.lang.String` #26

What is the bug?

When providing an object_id_field in the ext of a search request, the plugin will throw class java.util.ArrayList cannot be cast to class java.lang.String

This is actually an issue with the data set that is being used for testing. The value of the object_id_field is an array and should be a string. However, there should be better error handling to fail gracefully in that case.
