How to get a variable from WSDL with mule setvariable and datamapper? Message payload is of type: HashMap - soap

Question

It should be simple but I can't set it working. My XML looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<mule xmlns:ws="http://www.mulesoft.org/schema/mule/ws" xmlns:http="http://www.mulesoft.org/schema/mule/http" xmlns:data-mapper="http://www.mulesoft.org/schema/mule/ee/data-mapper" xmlns="http://www.mulesoft.org/schema/mule/core" xmlns:doc="http://www.mulesoft.org/schema/mule/documentation"

<data-mapper:config name="JSON_To_XML" transformationGraphPath="json_to_xml.grf" doc:name="JSON_To_XML"/>
<flow name="ws_pm_login3Flow">
<http:listener config-ref="HTTP_Listener_Configuration" path="/" doc:name="HTTP"/>
<set-payload value="#[{"userid":"xyz.qwe", "password":"12345"}]" doc:name="Set Payload"/>
<data-mapper:transform config-ref="JSON_To_XML" doc:name="JSON To XML"/>
<ws:consumer config-ref="Web_Service_Consumer" operation="login" doc:name="Web Service Consumer"/>
</flow>
</mule>
The WS is working fine.
The mapper file json_to_xml.grf looks like:

When I start the process I get:
Error executing graph: ERROR (com.mulesoft.mule.module.datamapper.api.exception.DataMapperExecutionException). Message payload is of type: HashMap
I am using 3.6.1 EE
What am I missing?

Turns out it is a problem in mule to use the double quotes in JSON. I swithced to XML and now it is working fine.
