Hi there,

I've recently installed the Backend_Redesign on my pi4, and it is all up and running fine, with the exception that at the end of the session it crashes out when it goes to save the recording files. So nothing is ever saved. I've pasted the journalctl output below. My coding ability is pretty limited, but I can't work out why the files aren't being saved, so any help or insight would be greatly appreciated. Other than that, your redesign works really well with my rowing machine!

Okay further to this, it appears to be an issue with the new RowingData file, as setting createRowingDataFiles to false in the config file stopped the app from crashing out, and also allowed the TCX and RawData CSV files to save without issue.
