Hi @CtrlXplorer
I followed these two guides to reproduce your error:
SDK: Service2Service Authentication
How to subscribe to nodes of the ctrlX Data Layer via web interface
But I was not able to reproduce your error. It worked fine for me. Please check if you have an error in the Data Layer path to the node you want to subscribe to. I would recommend to use this button to copie out the path: copy Data Layer path in web ui
Best regards,
Nick
