Database error

Im fairly new with OutSystems.  I am working with a DB2 database.  I have an application in OutSystems that has been live useing a AS400 file updating a field for processing.  The AS400 file changed.  We uploaded the new version but now I keep getting an odd error.  Any help would be appreciated.

 Here is the error...

The given key was not present in the dictionary.

An internal error occurred and was logged.
Please try again later or contact the administration team.

Sorry for any inconvenience.
