[Echo] Am I using the macro correctly?

,
1

So I want to add an isOnFloor data to the body using the example

--macro echo.Macros.add_data("isOnFloor", "Bool")

but when I try to access it I get an error:
problem

This is the hxml file if it will help

-cp src

-lib heaps
-lib hlsdl
-lib deepnightLibs
-lib ldtk-haxe-api
-lib echo

-hl bin/Test.hl

-main Main
-D windowSize=1024x576

--macro echo.Macros.add_data("entity", "objects.Entity")
--macro echo.Macros.add_data("isOnFloor", "Bool")
