Issue with connecting signal BodyEntered (area)

[DarthvaderBn]

Code:

gdobj Onion of Spatial:

    var swampObject: Swamp
    var area_touch: Area

    method ready*() =
        self.area_touch = self.getNode("Area") as Area
        discard self.area_touch.connect("body_entered", self , "on_area_touch_body_entered")
    
    proc onAreaTouchBodyEntered*(body: Node) {.gdExport.} =
        self.swampObject.takedOnion()
        self.queueFree
        print("Less goo")

I'm getting error
Could not access value because it is nil. (body: Node)

Changing proc to method

    method onAreaTouchBodyEntered*(body: Node) {.gdExport.} =
        ...

I found out the problem
i need to change Node to other type

Example:
I need to check if player is entered
So, i need to change type to KinematicBody

proc onAreaTouchBodyEntered*(body: KinematicBody) {.gdExport.} =
        self.swampObject.takedOnion()
        self.queueFree
        print("Less goo")
