error when using ContentStreamDataSource in DIH

[Piyush Kumar Nayak <pn...@adobe.com.INVALID>]

Hi,

I am trying to get data import to work with the data source embedded in the stream of the current request. I've enabled the dataImport request handler in the solrConfig.xml of the bookClub collection I'm testing this on, and reloaded the collection.
But I keep running into the error detailed below.

I'm posting the following POST request (in URL encoded format) using an HTTP client:
________________________________________________________________________________________________________________________________________________________
/solr/bookclub/dataimport?_=1565062909538&indent=on&wt=json&command=full-import&verbose=false&clean=false&commit=true&debug=true&core=bookclub&dataConfig=<dataConfig>
<dataSource name="streamsrc" type="ContentStreamDataSource" loggerLevel="TRACE" />
<script><![CDATA[
                function execute(row)    {
                //do something....
                }
        ]]></script>
<document>
    <entity
        stream="true"
        name="streamxml"
        datasource="streamsrc1"
        processor="XPathEntityProcessor"
        rootEntity="true"
        forEach="/books/book"
        transformer="script:execute" >
            <field column="load" template="some static payload"/>
            <field column="b_title" xpath="/books/book/name"/>
    </entity>
</document>
</dataConfig>&name=dataimport

However I'm running into the following in the error log:

Would appreciate any suggestions on what I am doing wrong.
