<on_error node=""/>

The node to advance to when there is an error in the application (e.g., a reference to an undefined node, variable, etc.).

This feature allows applications to fail more gracefully and to continue running in spite of errors.

When an error occurs, a description of the error is automatically written into the variable ERROR_MSG, which can be displayed or evaluated for logging or other purposes.
