Return a copy of "customItems". - Vulnerability - Minor

[JeetendrakumarSa]

For the below code getting Vulnerability, can someone assist with what to write instead:

@Override

    public List<OptionItem> getCustomItems() {

        return customItems;

    }

Passing this

  @Override
  public List<OptionItem> getCustomItems() {
    return List.copyOf(customItems);
  }

  @Override
  public List<OptionItem> getCustomItems() {
    return customItems != null ? List.copyOf(customItems) : List.of();
  }

getting null pointer exception

try like this:

@Override
public List<OptionItem> getCustomItems() {
return customItems != null ? new ArrayList<>(customItems) : new ArrayList<>();
}
