The only way I can think of fixing this, is to explicitly name the ports in your code to be the exact same string as the one the ports are currently serialized with in your project. So if your ports are currently serialized with an “İ”, change the code to an explicit string using that character. If you are uncertain how the ports are currently serialized in your project, you can view the json of an existing graph you have via the “File/View Json” command from the toolbar of the Graph Editor.
