Internal Server Error occurs while passing string to SetBody()

[#1]

Hello Experts,

I'm trying to build an xml body using groovy script from different sender. I could build xml file and convert to string, same way I could test in IntelliJ without an issue. when I deploy the same code in CPI, I'm getting the below Error.

com.sap.it.rt.adapter.http.api.exception.HttpResponseException: An internal server error occured: No signature of method: com.sap.gateway.ip.core.customdev.processor.MessageImpl.SetBody() is applicable for argument types (java.lang.String) values: [<ProdCatalog>....

Groovy Script

import com.sap.gateway.ip.core.customdev.util.Message;
import java.util.HashMap;
import groovy.xml.MarkupBuilder
import groovy.xml.XmlSlurper


def Message processData(Message message) {
    //Body 
def body = message.getBody();

def root = new XmlSlurper().parseText(body)
def writer = new StringWriter()
def builder = new MarkupBuilder(writer)

builder.ProdCatalog {
    'ArrayOfPCatInfo' {
        root.Root.each { item ->
            'PCatInfo' {
                'PFC'(item.PFCCode)
                'PF'(item.ProductFamily)
                'S'(item.Security)
                'PC'(item.TFSProductID)
                'P'(item.ProductDescription)
            }
        }
    }
    'ArrayOfPCatVersion' {
        root.Root.Version.Version.Package.Package.Module.Module.each { item ->
            'PCatVersion' {
                'PC'(item.parent().parent().parent().parent().parent().parent().TFSProductID)
                'VC'(item.parent().parent().parent().parent().VersionCode)
                'VC'(item.parent().parent().parent().parent().VersionDescription)
                'PKC'(item.parent().parent().PackageCode)
                'PK'(item.parent().parent().PackageDescription)
                'MC'(item.ModuleCode)
                'M'(item.ModuleDescription)
            }
            //println item.parent().parent().PackageDescription
        }
        root.Root.Version.Version.Package.Package.each { item ->
            if (item.Module.Module.size() <= 0) {
                'PCatVersion' {
                    'PC'(item.parent().parent().parent().parent().TFSProductID)
                    'VC'(item.parent().parent().VersionCode)
                    'VC'(item.parent().parent().VersionDescription)
                    'PKC'(item.PackageCode)
                    'PK'(item.PackageDescription)
                    'MC'("NULL")
                    'M'("NULL")
                }
            }
        }
        root.Root.Version.Version.each { item ->
            if (item.Package.Package.size() <= 0) {
                'PCatVersion' {
                    'PC'(item.parent().parent().TFSProductID)
                    'VC'(item.VersionCode)
                    'VC'(item.VersionDescription)
                    'PKC'("NULL")
                    'PK'("NULL")
                    'MC'("NULL")
                    'M'("NULL")
                }
            }
        }
    }
}
//    println("-----------------" + dc)
def op = writer.toString()
message.SetBody(op)

return message;
}

As I'm still in learning phase of CPI, any explanation/guidance/recommended approach along with solution would be much helpful

Thanks,

Hi senz.evo,

Hope you are doing well!

Could you please try message.setBody(op) ?
