Hello All, I’m new to XOD and have an issue with nkrkv’s “sleep-until-switch” (on UNO & NANO). I have seen several posts with the same issue but no recent solutions. This node is exactly what I need but errors in compiling. Could anybody direct me to the issue here, any help would be greatly appreciated. Comp errors below

The generated C++ code contains errors. It can be due to a bad node implementation or if your board is not compatible with XOD runtime code. The original compiler error message is above. Fix C++ errors to continue. If you believe it is a bug, report the problem to XOD developers.
