Exception is thrown when using TimestampUpdateProcessorFactory

[preeti kumari]

Hi All,

I am trying to get solr index time as solrtimestamp field.


<field name="solrtimestamp" type="tdate" indexed="true" stored="true"
omitNorms="true"/>

I am using solr 5.2.1 in solr cloud mode.


 <updateRequestProcessorChain name="script">
 <processor class="solr.TimestampUpdateProcessorFactory">
               <str name="fieldName">solrtimestamp</str>
  </processor>
      <processor class="solr.StatelessScriptUpdateProcessorFactory">
        <str name="script">update-script.js</str>
        <lst name="params">
          <str name="config_param">example config parameter</str>
        </lst>
 <str name="field">xnum,xnum2</str>
      </processor>
<processor class="solr.LogUpdateProcessorFactory" />
<processor class="solr.RunUpdateProcessorFactory" />
 </updateRequestProcessorChain>

But I am getting below exception when i run update or through DIH. Please
let me know how to fix this.
