Integration Studio conversion logic does not allow optional parameters to pass

[SupunTharakaSandaruwan]

Description

Freemarker template used in PayloadaFactory mediator does not allow to pass optional parameters empty,

Steps to Reproduce

• Using the IntegartionStudio 8.2.0 create a SoapToREST API using the RemoteUserStoreManagerService wsdl
• For the getUserCalimValues,
  • userName and profileName values are optional [2] but in the auto-generated logic, it is not considered
    auto-generated logic from IntegrationStudio 8.2.0

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
    <soapenv:Header/>
    <soapenv:Body>
        <web:getUserClaimValues xmlns:web="http://service.ws.um.carbon.wso2.org">
            <web:userName>${payload.getUserClaimValues.userName}</web:userName>
            <web:profileName>${payload.getUserClaimValues.profileName}</web:profileName>
        </web:getUserClaimValues>
    </soapenv:Body>
</soapenv:Envelope>

Request Json Payload

{
  "getUserClaimValues": {
    "userName": "admin",
    "profileName": "default"
  }
}

Since the profileName is optional, if we invoke the API in MI with the following request payload, it will gives the following error at MI
Request Json Payload

{
  "getUserClaimValues": {
    "userName": "admin",
  }
}

Error

 Error parsing FreeMarker template, Syntax error or invalid reference : payload.getUserClaimValues.profileName

Steps to Resolve

Update the freemarker template to allow the optional parametes.

As an example, in order to allow the profileName attribute optional, update the the generated payload as follows

<soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope">
    <soapenv:Header/>
    <soapenv:Body>
        <web:getUserClaimValues xmlns:web="http://service.ws.um.carbon.wso2.org">
            <web:userName>${payload.getUserClaimValues.userName}</web:userName>
            <#if $payload.getUserClaimValues.profileName?has_content>
            <web:profileName>${payload.getUserClaimValues.profileName}</web:profileName>
            <#else>
            <web:profileName\>
            </#if>
        </web:getUserClaimValues>
    </soapenv:Body>
</soapenv:Envelope>
