Solution
When LabVIEW migrates to LabVIEW NXG, the invoke nodes has been replaced by specific VI representations. For example, the Run VI invoke nodes has been replaced with Run VI functions to invoke the method to VI class.
Figure: Invoke node in current LabVIEW
Figure : Run VI representations in LabVIEW NXG
The fastest way to find the representation is to use the Ctrl + Space in LabVIEW NXG and search the method. Not all methods are currently available but will be updated accordingly in incoming NXG version.
