I'm trying to run some code that was successfully developed on LabVIEW 2019 using an updated install of LabVIEW 2023Q1. The code that used to work properly now gives me Error -1074099243 when I try to call the niDigital Load Pattern VI. The error explanation says the specified instrument index is invalid and gives the instrument index value as -1. However, I don't see the instrument index as a parameter anywhere in either my digital pattern files or in the niDigital VI palette or property nodes. If I launch the digital pattern editor and run the patterns from within that utility, the patterns load properly, and I observe the expected signal outputs. Is this issue caused by the update from 2019 to 2023Q1? I've tried re-saving the project using the digital pattern editor, but that doesn't seem to help with this issue.
Any advice will be greatly appreciated.
