Service update - > Expression.Error: <pii>

Hello Guys, 

I´m struggling to update my dashboard from service, and I don´t quite understand why this error pops up.

Expression.Error: <pii>The field 'XXXXXXX' of the record wasn't found.</pii>. . The exception was raised by the IDbCommand

Thanks in advance to all of you!!
