EPMSync Errors

"object reference not set to an instance of an object" When clicking on Edit Mappings:
queryString = String.Format(CultureInfo.InvariantCulture, "SELECT ID FROM sfATTRIBUTES WHERE AccountID = {0} AND InternalName='WORKFLOW_STATUS'", accountId); command = new SqlCommand(queryString, connection);
int WFAttributeID = (int)command.ExecuteScalar();

Error is thrown when ExecuteScalar returns null. Make sure you set the Portfolio Server Account Id properly and that query does in fact return something.

"The given key was not present in the dictionary" When clicking on Edit Mappings:
The default EPMSync.config that came with the installation already contained some Field Mappings. Delete everything between the tags and it should work.
