EditorScript _edit() method can receive null objects but the signature in gdext is Gd<Object> instead of Option<Gd<Object>>

[lmsonic]

The method _edit(object:Object) in EditorScript can accept null values, but the API in gdext accepts Gd<Object> which cannot be null
This is my usage right now, but it gives me errors in any case on the godot side:

fn edit(&mut self, object: Gd<Object>) {
        if !object.is_instance_valid() {
            return;
        }
        if let Ok(curve) = object.try_cast() {
            self.curve = Some(curve);
        }
    }

Error:

C:\Users\<REDACTED>\.cargo\registry\src\index.crates.io-6f17d22bba15001f\godot-core-0.1.3\src\private.rs:313 - godot-rust function call failed: SolidCurve2DEditorPlugin::edit()
