The Code Conversion Utility did not convert the specified project item or any project items that are a part of it because the specified item type is not supported in this version of LabVIEW NXG.
Review the references to this project item in the converted code and determine if a supported project item can replace the unsupported project item.
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.
