FilterProp:string | string[] | number | boolean | undefined
null is not a valid filter prop
Use negative filter "!" combined with wildcard filter "" to define a filter for the absence of a value
ex: an order list call with { xp: { hasPaid: '!' } } would return a list of orders where xp.hasPaid is null or undefined
