On run within the App Designer, I get the message: - "Unrecognized function or variable 'VideoSignal.empty'. In base workspace"

VideoSignal is a (handle) class which is defined in the app as a property.

It does not have any empty method or variable, and no "empty" word appears in any of the software including the app.

The "Pause on error" run option does not show where the error generating code is.

I have no idea what the problem is.

The VideoSignal class had a syntax error (typo). Still, I would have expected a more useful error message from the app builder thing.
