Hi Shrey
As I can understand from your explaination, you are trying to use background processing for your code and you are not getting the expected outputs. One reason for that could be as you are passing system objects in background and then fetching their outputs, but system objects are not supported in background. You have to pass functions only.
One alternative for it could be that you convert your classes into functions and then pass to background.
I also request to share your code and error which you got, it wil be more useful in resolving your query.
