I have to generate a CSV file without the header line.
So I created the following xsd :
<?xml version="1.0" encoding="utf-16" ?>

The file is generated correctly :

</Person>
</ns0:Person_Export>
But the pipeline return this error :
Unable to read the stream produced by the pipeline. Details: Value cannot be null. Parameter name: format
The fields over_end_date, EMP_UDF_DATA1 and USER_STATUS must be blank in the output so in the mapping I setted the Value property to empty.
I tested this solution but doesn't resolved my issue.
Ok I managed to find a solution by changing the date type to string type.
The fact that some date in my output must be empty was the reason for this error.
