Debugging Host-Side in the Adobe CEP

Hi

i am trying to debug the "host-side" extendscript for a panel i made , i've manage to debug the front-side and debug specific jsx file using VS with "ExtendScript Debugger" the problem is that i need to debug somthing that goes from the front-side js (an array) to the host side using the .evalScript from the csInterface library :

csInterface.evalScript(`exportFile("${myJSON}")`);

 is there any way to debug the host side for the errors ? 

i tried adding alert() inside the jsx , it works only if i send string, so i tried convert the array into a long string but still not working, only works if i take form example one element from the array and send him

those the evalScript , accept only strings ? meaning i can only pass string from the front to the host ?
