I finally got it working. The problem ended up being that when I copied the example for the resource, I was using the MS Edge browser and it ended up putting some weird characters (0xC2 0xA0) for each leading space on each line . When I just retyped it, or used Chrome to copy it so the spaces were 0x20, everything was fine. I also was able to use "Raw Text" rather than "C-Escaped" to keep the code in the Body window in a sane format.
