It seems like App\Models\Lookup\Frequency::all()->pluck('id') of type Illuminate\Support\Collection is incompatible with the declared type App\Services\Validation\Rules\Collection of property $validIds.
Our type inference engine has found an assignment to a property that is incompatible
with the declared type of that property.
Either this assignment is in error or the assigned type should be added
to the documentation/type hint for that property..
