thanks @tqAkshay95 and @rfeigel

@suseearun it looks like you are still using a saved copy of the component demo that you saved before the Continental nodes were fully installed, and as such this resulted in the disconnected nodes within the component.

re the Java.io.inputstream error, I don’t see that error when I attempt to run that workflow. As I said in the other post though, that workflow is corrupted (due to the Continental nodes not having been installed when you saved it), so you need to use a new copy of it, or at least pull down a fresh copy of the component from the hub.

As a reminder, the (uncorrupted) original of that demo workflow can be downloaded from here:

Also, I find it a little confusing that in your first screenshot containing the error, the workflow that is behind the error message:

Perhaps you can clarify when this error occurs?
