I am having trouble with a!queryFilter( field: &quo

I am having trouble with
a!queryFilter(
field: "hasBeenFittedSuccessfully",
operator: "<>",
value: true()
),
I have a data row that has NULL for "hasBeenFittedSuccessfully". So it not displayed even if it is different from "true".
How can I handle that?
