REST API returning an error message to client

[Matthew Shaw <Ma...@ambulance.qld.gov.au>]

Hi All,

Running synapse3 with a rest api. I have a faultsequence defined which is being invoked when my backend call returns an error. The 500 internal server error is being sent back to my client, however, I cannot seem to send my error message back.

Here is my xml config fragment

<resource uri-template="/dutyhours/costcode/lasn/search?query={symbol}" methods="GET"
          content-type="text/plain; charset=utf-8">
    <inSequence>
        <header name="Access-Control-Allow-Origin" value="*" scope="transport"/>
        <payloadFactory>
            <format>
                <m0:RecordTAMediatorRequest
                        xmlns:m0="http://services.ambulance.qld.gov.au/mediator/hcm/mra/mta/rta">
                    <m0:query>$1</m0:query>
                    <m0:indexName>QASCostCode</m0:indexName>
                    <m0:responseFormat>json</m0:responseFormat>
                </m0:RecordTAMediatorRequest>
            </format>
            <args>
                <arg expression="url-encode(fn:concat('q=t_lasn:&#34;',get-property('uri.var.symbol'),'&#34;'))"/>
                <arg expression="get-property('uri.var.index')"/>
                <arg expression="get-property('uri.var.responseFormat')"/>
            </args>
        </payloadFactory>
        <property name="SOAPAction" value="searchForCostCentre" scope="transport"/>

        <send>
            <endpoint>
                <address
                        uri="http://PC004406:8280/services/RecordTAMediatorProxy.RecordTAMediatorProxyHttpSoap11Endpoint"
                        format="soap11"/>
            </endpoint>
        </send>
    </inSequence>
    <outSequence>
        <header name="Access-Control-Allow-Origin" value="*" scope="transport"/>
        <!--<xslt key="json_only"/>-->
        <filter source="get-property('uri.var.responseFormat')" regex="xml">
            <then>
                <property name="messageType" value="application/xml" scope="axis2"/>
                <respond/>
            </then>
            <else>
                <property name="TRANSPORT_HEADERS" action="remove" scope="axis2"/>
                <property name="messageType" value="text/plain" scope="axis2"/>
                <property name="ContentType" value="text/plain" scope="axis2"/>
                <header name="Access-Control-Allow-Origin" value="*" scope="transport"/>
                <xslt key="rta_rest_api_transform"/>
                <respond/>
            </else>
        </filter>
        <send/>
    </outSequence>
    <faultSequence>
        <property name="messageType" value="text/xml" scope="axis2"/>
        <property name="ContentType" value="text/xml" scope="axis2"/>
        <property name="Content-Type" value="text/xml" scope="transport"/>
        <property name="HTTP_SC" value="500" scope="axis2"/>
        <makefault response="true" version="pox">
            <code xmlns:tns="http://www.w3.org/2003/05/soap-envelope" value="tns:Receiver"/>
            <reason expression="get-property('ERROR_DETAIL')"/>
        </makefault>

        <log level="full"/>
        <send/>
    </faultSequence>
</resource>

In my log statement in the faultsequence I see this

INFO LogMediator To: /rest/mediator/hcm/mra/mta/rta/dutyhours/costcode/lasn/search?query=south, MessageID: urn:uuid:c2b2c888-02d2-4c8f-a715-8528e10c1512, Direction: request, Envelope: <?xml version='1.0' encoding='utf-8'?><soapenv:Envelope xmlns:soapenv="http://www.w3.org/2003/05/soap-envelope"><soapenv:Header/><soapenv:Body><tp:fault xmlns:tp="http://test.com"><tp:code>500</tp:code><tp:type>Status report</tp:type><tp:message>Internal Server Error</tp:message><tp:description>Barf.</tp:description></tp:fault></soapenv:Body></soapenv:Envelope>

Which is what I want to see in my rest client (soap-ui).

However, all I see in my client are the headers, body is empty / null. Any ideas? I'm guessing it has something to do with my contentType and my axis2 config for messageFormatter's and or messageBuilder's?

I've also tried replacing makefault mediator with a payloadfactory, but same problem.

Cheers,
Matt.
