cannot update record with dbutils

Hello!

I cannot understand why I cannot update a record on a table this way:

Sub BtnSalva_Click
Dim WhereFields As Map
WhereFields.Initialize
WhereFields.Put("IdConfig", "EMMECI")
DBUtils.UpdateRecord(SQL, "Impostazioni", "IdAge", "ciro", WhereFields)
End Sub

I got an error msg in the dbutils module at line 127!

ps you can find the same post in the dbutils discussion!
