title: Invoking API from WSO2 store causing "101500 - Error in Sender"
body: <p>I have configured our API inside WSO2 API manager, created one Application, generated keys and subscribe to one API from the application. Now while I am invoking the API from the WSO2 API store API Console, getting below error:</p>
  
  <pre><code>&lt;am:fault xmlns:am="http://wso2.org/apimanager"&gt;
    &lt;am:code&gt;101500&lt;/am:code&gt;
    &lt;am:type&gt;Status report&lt;/am:type&gt;
    &lt;am:message&gt;Runtime Error&lt;/am:message&gt;
    &lt;am:description&gt;Error in Sender&lt;/am:description&gt;
  &lt;/am:fault&gt;
  </code></pre>
  
  <p>By initial investigation and googling I thought of some certificate error for which the API manager couldn't get the response from the API deployed server, but no luck. And also the server where APIs are deployed is a http tomcat server. Can anyone help me to resolve this issue?</p>
  
  <p>Thanks &amp; Regards,
