I've found an interesting bug - running OP4 on a RPi5, SignalK crashes when I load the N2K sample file aava-n2k.data.
I've raised a bug on the n2k-signalk project (see here). But I don't remember seeing the issue on my previous installation (OpenPlotter 3 on RPi 4), so could it be the new hardware or OP4? Or is it more likely to be a recent SignalK change?
EDIT - RAISED IN ERROR
It was my own stupid fault, I was incorrectly using data type "NMEA 2000 (canboat)". As suggested by sbender, I changed to "Actisense NMEA 20000 (canboatjs)" and it now works perfectly.
