Issue while saving the chart

Hi there, I am using your editor4 in angular and facing some issue while trying to save the chart. The image is attached below. When click on the save button i got the error. The error is listed in the console. Thank you..!

Is this in your own app or a demo included with the Editor? This feels like when you create a launcher you either don't store a reference to it or access it incorrectly (maybe this is referring to something else than it's supposed to be?).

Unfortunately, I have no experience with Anglular so definitely can't tell anything from so few details.
