Hi Aditya,
I tested your API configuration with a mock backend which returns a simple
JSON payload and I didn't get the mentioned error. Please find the
configurations [2].
[1]
{
"test": "test"
}
[2]
API:
<api xmlns="http://ws.apache.org/ns/synapse"; name="cacheAPI2"
context="/cache2">
<resource methods="POST GET" uri-template="/headerapi2/*">
<inSequence>
<log>
<property name="Cache_Flow" value="Inside Cache Flow
............................."/>
</log>
<cache id="cache-sample" scope="per-host" collector="false"
hashGenerator="org.wso2.carbon.mediator.cache.digest.REQUESTHASHGenerator"
timeout="5000" maxMessageSize="100000000">
<implementation type="memory" maxSize="1000"/>
</cache>
<log>
<property name="CacheFinder" value="After Cache Finder
******************"/>
</log>
<property name="uri.var.agreementId" value="1392" scope="default"
type="STRING"/>
<call>
<endpoint key="AgreementEP"/>
</call>
<log description="">
<property name="Call_Mediator" value="After Call Mediator
*********************"/>
</log>
<property name="RESPONSE" value="true" scope="default"
type="STRING"/>
<log level="full">
<property name="msg" value="Direct Response"/>
</log>
<cache scope="per-host" collector="true"/>
<respond/>
</inSequence>
<outSequence/>
<faultSequence/>
</resource>
</api>
Endpoint:
<endpoint xmlns="http://ws.apache.org/ns/synapse"; name="AgreementEP">
