> Currently, when a name that does not exist on the Schema is passed to {{Schema::index_of}}, the error message is just the name itself. This makes it a bit difficult to debug.
>  
> I propose that we change the that error message to something like
> {{Unable to get field named "nickname". Valid fields: ["first_name", "last_name", "address"]}}
> to make it easier to understand.
