The Code Conversion Utility encountered an unexpected error while inserting a node on the diagram. Wires may be broken.
The Code Conversion Utility attempted to insert additional nodes on the diagram to ensure runtime behavior is not changed. The node insertion failed for an unknown reason, so there may be broken or disconnected wires on the diagram.
Review the block diagram for broken wires.
If the previous suggestions don't restore the functionality of the affected code and the code isn't essential to the core functionality of your application, you can remove the portion of code. If the code is part of the core functionality of the application, you can use the VI Interop node to call your existing code, provided that the new code organization meets the architectural goals of your application. If neither solution meets the requirements of your application, do not migrate to LabVIEW NXG at this time.
