Removing a child node from a object cannot be undo

Removing a child node from a JSON object cannot be undo,

My store code is given below.
export const formStore = defineStore('form', { state: () => ({ form: { title: "", spellCheck: true, set: [], id: "" } as FormInterface , }), getters: { }, actions: { }, })

First i push data to the set array and after i removed the item using the array splice function, Then I tried to undo and the undo function doesnt work. An error message indicates that some keys are missing.
