WSO2 ESB Fronting a Rest Service with OAuth token validation - 202 Response

Question

I am experimenting with WSO2 ESB to secure by REST APIs, by following this approach: https://docs.wso2.com/display/ESB480/Securing+REST+APIs

My API configuration:

<?xml version="1.0" encoding="UTF-8"?>
<api xmlns="http://ws.apache.org/ns/synapse"
     name="Test"
     context="/test">
   <resource methods="GET">
        <inSequence>
            <log level="full">
               <property name="STATUS" value="***** REQUEST HITS IN SEQUENCE *****"/>
             </log>
         <send>
            <endpoint>
               <http method="get" uri-template="http://localhost:8080/document"/>
            </endpoint>
         </send>
      </inSequence>

   </resource>
    <handlers>
      <handler class="org.wso2.handler.SimpleOauthHandler"/>
   </handlers>
</api>

When I remove the handler section, I can see my service being invoked. But when I include the ouath handler, I can see my WSO2 Identity Server receiving the token validation call but the response from ESB is always HTTP 202.

curl -v -X GET -H "Authorization: Bearer UQFffmYViFDxTHfCLOwDpjcX3qXZYQuiJ8EgJ_m-F1V7JTgqb6lbyA8QMT3" http://localhost:8285/document

> GET /document HTTP/1.1
> User-Agent: curl/7.33.0
> Host: 192.168.2.162:8285
> Accept: */*
> Authorization: Bearer UQFffmYViFDxTHfCLOwDpjcX3qXZYQuiJ8EgJ_m-F1V7JTgqb6lbyA8QMT3
>
< HTTP/1.1 202 Accepted
< Date: Fri, 10 Apr 2015 20:44:57 GMT
* Server WSO2-PassThrough-HTTP is not blacklisted
< Server: WSO2-PassThrough-HTTP
< Transfer-Encoding: chunked

Any pointers on what am I missing or how I can debug would be appreciated.

Thank you.

It was in fact issue with my access token. Using the right token worked right. Also OAuth mediator can be used instead of handler.

<api xmlns="http://ws.apache.org/ns/synapse"
     name="Test"
     context="/test">
   <resource methods="GET">
        <inSequence>
            <log level="full">
                <property name="STATUS" value="***** REQUEST HITS IN SEQUENCE *****"/>
            </log>
            <oauthService remoteServiceUrl="https://localhost:9445/services/" username="admin" password="admin"/>    
         <send>
            <endpoint>
               <http method="get" uri-template="http://localhost:8080/document"/>
            </endpoint>
         </send>
      </inSequence>
   </resource>
</api>
