iTween StopByName

Hi everyone, I stumbled on an issue when using iTween.StopByName. The issue is that if I try to use it by StopByName(" "+gameObject.GetInstanceID()) throws me a MRE saying an object of type GameObject has been destroyed but I'm still trying to access it, even though no GO were destroyed. I suppose the way I call the stop gets in conflict with iTween. Using iTween.Stop(gameObject) works for me, but I wanted to know if there's a way to get it to work. Thank you and have a nice day!
