Get read time out when Call restful API in the sequence with Iterate mediator in wso2 ESB

Question

I'm new in the WSO2 ESB. I need your help. I get data from database by DSS and send them into a rest web service with call (in block mode) or send mediator. I split my records to individual messages in ESB by Iterate mediator and set iterate mediator properties to ture and then send date as parameters to my API. I can see in the log iterate mediator splits records to individual messages and put them in my html endpoint correctly. But I get a "read time out response" in ESB after calling my end point. If i don't use iterate mediator and I put parameters directly in the properties as test and send them to my rest API, It works fine. But when I use Iterate mediator to get parameters from DSS and send them to API, it faces with time out error. I checked log mediator to see what happened, the error is unable to send via post to my endpoint and read time out. I copied the URL for my endpoint from ESB log and tried to invoke it by SoapUI, It works fine without any time out issue.

My api is civicrm api: my Api parametrs are defined :

contact_type={uri.var.contact_type}
first_name={uri.var.first_name}
last_name={uri.var.last_name}

I used Call mediator for call api by blocking mode true. I sent first_name, last_name, contact_type from DSS:

<Submissions>
 <Submission>
  <contact_type>Individual</contact_type>
  <first_name>Testname</first_name>
  <last_name>TestFamily</last_name>
</Submission>
</Submissions>

After iterate mediator I put log mediator and can see the above value. After calling endpoint, I received this error: http://localhost/CIVICRM/sites/all/modules/civicrm/extern/rest.php?entity=Contact&action=create&key=1111&user=test&pass=passsss&api_key=1111111111&version=3&contact_type=Individual&first_name=Testname&last_name=TestFamily, MessageID: urn:uuid:daa47ef5-1f7a-4f2c-9372-ba17f0e282ee, Direction: response, MESSAGE = Executing default 'fault' sequence, ERROR_CODE = 401000, ERROR_MESSAGE = Read timed out

When I put this endpoint in SoapUI, It works. When I don't use DSS and iterate mediator and Put parametrs directly in sequence, it works.

I appreciate your help. Thanks

This can hapen when a response is not sent from your backend. So you can set the following property before the send mediator to get rid of this.

<property name="OUT_ONLY" value="true"/>

Thanks, I put Out_Only peroprty before that. But it still can not post my request. once I tried it without iterate mediator and put my parameters manually in sequence, it works fine.

Can you share your proxy configurations?

Yes, Thanks for your consideration. The sequence that works fine is:

<sequence xmlns="http://ws.apache.org/ns/synapse"
          name="importCiviCRM"
          trace="disable">
   <property name="uri.var.type"
             value="Individual"
             scope="default"
             type="STRING"/>
   <property name="uri.var.first"
             value="aaaaaa"
             scope="default"
             type="STRING"/>
   <property name="uri.var.last"
             value="bbbbbbb"
             scope="default"
             type="STRING"/>
   <property name="FORCE_HTTP_CONTENT_LENGTH"
             value="true"
             scope="axis2"
             type="STRING"/>
   <property name="COPY_CONTENT_LENGTH_FROM_INCOMING"
             value="true"
             scope="axis2"
             type="STRING"/>
   <property name="HTTP_METHOD" value="POST" scope="axis2" type="STRING"/>
   <property name="messageType"
             value="application/xml"
             scope="axis2"
             type="STRING"/>
   <header name="To" scope="default" action="remove"/>
   <property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
   <property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>

   <send buildmessage="true">
      <endpoint key="CiviImport"/>
   </send>
</sequence>

I tried my above sequence with property Response=True instead of OUT_ONLY and it works fine as well.

my endpoint is:

<endpoint xmlns="http://ws.apache.org/ns/synapse" name="CiviImport">
   <http uri-template="http://localhost/CIVICRM%20WAREHOUSE/sites/all/modules/civicrm/extern/rest.php?entity=Contact&amp;action=create&amp;key=111111&amp;user=Testuser&amp;pass=Testpass&amp;api_key=111111111&amp;version=3&amp;contact_type={uri.var.type}&amp;first_name={uri.var.first}&amp;last_name={uri.var.last}"/>
</endpoint>

But when I try to get first_name, last_name and contact_type from DSS and use Iterate mediator for splitting message into separate messages, I face with problem . This is my sequence:

<?xml version="1.0" encoding="UTF-8"?>
<sequence xmlns="http://ws.apache.org/ns/synapse" name="CiviCrmAPI">
   <iterate xmlns:dss="http://ws.wso2.org/dataservice"
            xmlns:ns="http://org.apache.synapse/xsd"
            continueParent="true"
            id="IterateRequestSink"
            expression="//dss:Submission"
            sequential="true">
      <target>
         <sequence>
            <property name="uri.var.type"
                      expression="//dss:contact_type/text()"
                      scope="default"
                      type="STRING"/>
            <property name="uri.var.first"
                      expression="//dss:first_name/text()"
                      scope="default"
                      type="STRING"/>
            <property name="uri.var.last"
                      expression="//dss:last_name/text()"
                      scope="default"
                      type="STRING"/>
            <log>
               <property name="uri.var.type" expression="get-property('uri.var.type')"/>
               <property name="uri.var.first" expression="get-property('uri.var.first')"/>
               <property name="uri.var.last" expression="get-property('uri.var.last')"/>
            </log>
            <property name="FORCE_HTTP_CONTENT_LENGTH"
                      value="true"
                      scope="axis2"
                      type="STRING"/>
            <property name="COPY_CONTENT_LENGTH_FROM_INCOMING"
                      value="true"
                      scope="axis2"
                      type="STRING"/>
            <property name="HTTP_METHOD" value="POST" scope="axis2" type="STRING"/>
            <property name="messageType"
                      value="application/xml"
                      scope="axis2"
                      type="STRING"/>
            <header name="To" scope="default" action="remove"/>
            <property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
            <property name="NO_ENTITY_BODY" scope="axis2" action="remove"/>
            <send buildmessage="true">
               <endpoint key="CiviImport"/>
            </send>
         </sequence>
      </target>
   </iterate>
</sequence>

I've added Disable-chunking property set value to true before Send mediator.

 <property name="DISABLE_CHUNKING" value="true" scope="axis2"/>

The problem was solved.
