1.14.4 How can I store world edit changes to flat file

My end goal is to be able to rollback changes from the world edit api after x amount of time.
So far, I'm storing everything in a .json format and I've tried formatting via gson. Here's what I've got so far:

Code (Text):

 private String serializeObject(EditSession editS) {
        return gson.toJson(editS);
    }

    private EditSession deserializeObject(String serializedObject) {
        EditSession session = gson.fromJson(serializedObject, EditSession.class);
        return session;
    }

Now, what happens when this code runs is I get a stack overflow error because of the cyclic dependencies and whatnot (through gson) I've also tried ChangeSet and even individual Change class from world edit.

How would I go about being able to store the changes made and then retrieving the changes at a later date?
