I'm trying to use the LabVIEW CLI on macOS with LabVIEW 2018 and 2020. In either case, when I execute my command, LabVIEW starts and then immediately after I get an error message that it can't establish a connection because the port is currently in use. I've checked the OS to see who was using the port in question and it only showed LabVIEW as using it. The same exact code does. work on Windows.
Here's the command and output from the LabVIEW CLI:
LabVIEWCLI -LabVIEWPath "/Applications/National Instruments/LabVIEW 2018 64-bit/LabVIEW.app/Contents/MacOS/LabVIEW" -PortNumber 3364 -LogFilePath "/var/folders/w_/895xs725223054n5dpkwv6gm0000gn/T/tmpi6gmheqk/log.txt" -LogToConsole true -OperationName RunVI -Verbosity Diagnostic -VIPath "/Users/jenkins/Perforce/mainline/VIs/MyVI.vi" "/Users/jenkins/Perforce/REL19/MyVI.json"
