Ahoy: I'm trying to write a filter query which needs to test for the non-existence of a one-to-many relationship, I can use

null

in the console... however when I try and do this through Apollo it throws expected type errors (eg it doesn't like

null

values, because the schema is a relationship). Does anyone have any experience with this?

Copy code

{ Error: GraphQL error: Argument 'filter' expected type 'AspectFilter' but got: {isActive: true, parent: ""}. Reason: 'parent' Expected 'AspectFilter', found not an object. (line 2, column 22):

Copy code

{ Error: The inline argument "parent" of kind "NullValue" is not supported. Use variables instead of inline arguments to overcome this limitation.
