Mapping JSON to XML with DataMapper, expect I have no output column

VictorFaure — Wed, 25 Jun 2025 15:07:57 GMT

Hello,

I'm working on exposing a REST API which is basically a wrapper around a SOAP API. I need to convert the JSON payload I receive into a XML payload to call the SOAP service with, tHMap component seemed perfect for the job, as it is supposed to be able to map JSON to XML (see picture mapping)

Except it doesn't have any output column defined. The output schema is completely empty

I have the "Write Output As" property setup to String (Single column) which I assume should output a column...
Anyways I'm currently searching how to make this component output anything at all... Thanks for your help.

Hello @VictorFaure ,

I often use tHmap (datamapper), it needs to be configured a bit like below.
