How to enrich a node value in OM property? - wso2

Question

Is it possible to enrich a specific node value with enrich mediator?
My goal is to enrich this xpath:
$ctx:OriginalPayload//Partner[identifiers/businessId = $ctx:CorrelationId]/identifiers/otherId
I have tried these examples:
$ctx:OriginalPayload//Partner/identifiers/otherId
//Partner/identifiers/otherId
//Partner/identifiers/otherId/text()
//Partner/identifiers/otherId/node()
All gave me this error:
ERROR - EnrichMediator Invalid Target object to be enrich.
I'm using this syntax:
<enrich>
<source xpath="//plat:CustomerAccountId"/>
<target xpath="//Partner/identifiers/otherId"/>
</enrich>
Below is my payload which i'm trying to enrich:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:ns0="http://iszkody.lsn.io/service/internal/ClaimService">
<soapenv:Header/>
<soapenv:Body>
<ns0:createClaimRequest>
<claim>
<InsClaimData VER="1">
<PartnerList>
<Partner>
<RoleList>
<Role>UBEZP</Role>
</RoleList>
<BusinessPartner>
<partnerType>person</partnerType>
<personData>
<firstName>JANUSZ</firstName>
<lastName>KOWALSKI</lastName>
<PESEL>83248328432</PESEL>
</personData>
<identifiers>
<businessId>123</businessId>
<otherId></otherId>
</identifiers>
</BusinessPartner>
</Partner>
</PartnerList>
</InsClaimData>
</claim>
</ns0:createClaimRequest>
</soapenv:Body>
</soapenv:Envelope>
It doesn't look like a problem with payload or xpath but more like the mediator doesn't implement custom type.

I just tested the following in WSO2 ESB 4.9.0 and also 4.8.1 and in both version the following proxy did work (I enrichted the otherId with the businessId):
<proxy xmlns="http://ws.apache.org/ns/synapse" name="Test_XPath" transports="http" xmlns:avintis="http://www.avintis.com">
<target faultSequence="faultSequence">
<inSequence>
<sequence key="initSequence" />
<log level="full"></log>
<log level="custom">
<property expression="$body//businessId" name="xpath" />
</log>
<log level="custom">
<property expression="$body//Partner/BusinessPartner/identifiers/businessId" name="xpath" />
</log>
<enrich>
<source xpath="//businessId" />
<target xpath="//otherId" />
</enrich>
<log level="full" />
</inSequence>
</target>
</proxy>
As you commented that you now use the *[local-name()='BusinessPartner'] syntax, this points out to be an issue with the namespaces. Try to use the correct namespace of the BusinessParter elements.
