Hi the issue is with the push statement in your function when updating states in the constructor or reducer use concat or spread operator[...]> I have made a sample over here please check

onAddItem() {
        let list = [...this.state.items, {text:`Check 1`}];
        this.setState({items:list});
}

in your case you can do the following

let arr = [...childList, newChild]

then dispatch the arr

 dispatch(setDoc(arr));
