Error Compiling Examples | Arduino Compatible Compiler for LabVIEW Discussions | Forum

Hi
I am new to the Ardrino compatible compiler of LabVIEW. Using LabVIEW Community Beta 2020 version.
I am trying to compile an example provided with the addon but I get a compiler error.
Ive tried it with 10 or more of the examples and get the compiler error.
This is what I am doing:
1. Connect Arduino UNO to PC and verify UNO is selected and COM3 as shown in device manager.
2. Start "Ardunio compatible Compiler for LabVIEW"
3. Select File, Load VI, and load example "Digital Input - Polling a Button.vi"
4. Select Compiler, Verify.
5. Message appears:
Running Interpreter...Finished!
Generating downloadable program...Finished!
Compiling...Error!

There has been an unexpected error compiling the input VI. Please refer to the user manual for help or contact support for further information.
6. Detailed debug in attached file.

There must be something simple I am doing wrong. Please help.

Thanks
