value for key 'values' was of unexpected class 'NSArray'

Hi team.

I trying to track down an error... intercept/fix. I suspect I have a corruption (from somewhere) in my sqllite database in icloud... I have not been able to figure out how to intercept the error.

For context there is only one table of data. It could be my icloud data that is corrupt, although how it would have got corrupt would also be a mystery.

Any advice on how I can track down this error?
