I usually encounter this type of error message when a view I am trying to query has an obligatory parameter, and I am not passing any value.
In order to resolve this, you can check your query and ensure that you’re passing a parameter value. Otherwise, I would also suggest setting a default value for your mandatory parameter to avoid the error message. You can refer to this User Manual, regarding [how to set parameter default values in a derived view](https://community.denodo.com/docs/html/browse/8.0/en/vdp/administration/creating_derived_views/creating_selection_views/creating_selection_views#parameters-of-derived-views).
As for the error message change, this is a new enhancement provided in the latest **20230301** update. It helps to easily debug search method errors by projecting the obligatory fields.
Hope this helps!
