how can example, located on mule esb documentation, work ?:

<http:request-config name="http_request_configuration" host="example.com" port="8081" doc:name="http_request_configuration"/>  <flow name="test_flow">     <set-variable variablename="custommap" value="#[{'k2':'new', 'k3':'v3'}]" /     <http:request request-config="http_request_configuration" path="test" method="get">         <http:request-builder>             <http:query-params expression="#[flowvars.custonmap]" />         </http:request-builder>     </http:request>  </flow> 

i giving me error!

  • message : null (java.lang.nullpointerexception). message payload of type:
  • string code : mule_error--2

exception stack is:

  1. null (java.lang.nullpointerexception) org.mule.module.http.internal.httpmapparam:41 (null)
  2. null (java.lang.nullpointerexception). message payload of type: string (org.mule.api.messagingexception)
    org.mule.execution.exceptiontomessagingexceptionexecutioninterceptor:32 (http://www.mulesoft.org/docs/site/current3/apidocs/org/mule/api/messagingexception.html)

typo:

<set-variable variablename="custommap" 

is subsequently used custonmap not custommap in:

expression="#[flowvars.custonmap]"
