WSO2, Data Source Error only with a subquery called from API - wso2

I have a datasource with a query that calls a subquery.
If I reach the datasource through a SOAP request (ex. SOAPUI), I have no problems whatsoever.
If instead I call the SOAP endpoint through a WSO2 API, or if I remove the subquery from the main query, I get the following log/errors:

I'll answer my own question
Somehow, the <m:request/> content will cause the error in that single, unic, specific use case...
Wrong:
<m:getOrganigramma xmlns:m="http://services.samples">
<m:request>
<m:cod_uo>$1</m:cod_uo>
<m:data>$2</m:data>
</m:request>

Correct:
<m:getOrganigramma xmlns:m="http://services.samples">
<m:cod_uo>$1</m:cod_uo>
<m:data>$2</m:data>
</m:getOrganigramma>

WSO2 EI: Dataservice using giving INCOMPATIBLE_PARAMETERS_ERROR when calling through REST API

I am using WSO2 EI 6.3.0 version. I am creating data service within the application which reads data from CSV.
I am running into very unusual case where I have created two data services. One with sample Product.csv which is shipped with WSO2 EI.
When calling Sample (Product.CSV) I am able to get the json response message. but when I am trying to invoke another API which other data service it is giving me below error:

Not sure where is the problem. Both are simple data service and didnot find any differences in creating them. One is working and one is not working at all.
Can some one please help me. Is this a bug?
Thanks in advance.

I am clueless about how to rectify this bug. Plz help
The WARN message that you get means that your xslt mediator is not able to find the file at the location 'conf:/repository/synapse/default/local-entries/CustomerOrderInputTransfer.xslt' .
If you are accessing it from local-entries folder, you can try specifying only CustomerOrderInputTransfer.xslt as the key attribute.

WSO2 Data service not working for named queries (prepare statements)

I was just trying to do a simple data service connecting to HR schema on Oracle XE DB. I just wrote a simple query with operation which takes an input parameter and gets the result accordingly as per the bind data passed.
My Query looks as below
SELECT first_name,last_name,email,phone_number,hire_date,salary
FROM employees
WHERE first_name like :Bind_name
I have added a input variable Bind_name and passing it when im requesting the service.
But, when i trigger the service i see below error and couldn't find relevant help on web.

Here find the .dbs file that I used,
<data name="DDD">
<config id="ds1">
<property name="org.wso2.ws.dataservice.driver">oracle.jdbc.driver.OracleDriver</property>
<property name="org.wso2.ws.dataservice.protocol">jdbc:oracle:thin:#localhost:1521/xe</property>
<property name="org.wso2.ws.dataservice.user">xxx</property>
<property name="org.wso2.ws.dataservice.password">xxx</property>
</config>
<query id="q1" useConfig="ds1">
<sql>select EMPLOYEENUMBER from employees where LASTNAME like :Bind_name</sql>
<result element="Entries" rowName="Entry">
<element name="EMPLOYEENUMBER" column="EMPLOYEENUMBER" xsdType="xs:string" />
</result>
<param name="Bind_name" sqlType="STRING" />
</query>
<operation name="op1">
<call-query href="q1">
<with-param name="Bind_name" query-param="Bind_name" />
</call-query>
</operation>
</data>
And the request is,
<p:op1 xmlns:p="http://ws.wso2.org/dataservice">
<!--Exactly 1 occurrence-->
<p:Bind_name>d%</p:Bind_name>
</p:op1>
It works fine as expected. Could you post your dbs file as well ?
