FWIW I wonder what actually is in the error reports.
During initial setup I chose a weak Wi-Fi AP - long story - and that caused an error that I could have sent to Nintendo... except, not really, because that required a working internet connection... I think I could look at it later but not resend it. It had a fair amount of details visible, but nothing particularly special (error number, FW at error, etc.). I imagine the reports must have some secret sauce inside, but whether it's enough to help with things like these, I have no idea.
