Problem with multi-valued field using Solr CEL

[Charlie Hubbard <ch...@gmail.com>]

So I'm trying to index documents using Solr CEL and Tika on Solr 5.4.1.
I'm using the default configuration, but when I import my docs I'm getting
this error:

Here is my solrconfig.xml of the extract module:

<requestHandler name="/update/extract"
                startup="lazy"
                class="solr.extraction.ExtractingRequestHandler" >
  <lst name="defaults">
    <str name="lowernames">true</str>
    <str name="uprefix">ignored_</str>

    <!-- capture link hrefs but ignore div attributes -->
    <str name="captureAttr">true</str>
    <str name="fmap.a">links</str>
    <str name="fmap.div">ignored_</str>
  </lst>
</requestHandler>

I thought this would basically mark everything that wasn't a field as
ignored so meta shouldn't be imported.  I've searched through my solr
schema, and I have no meta field declared hence I thought CEL would throw
it out.

I'm using Solrj to import the docs.  I'm also adding a lot of literals to
the document.  You can see above the data that I'm providing in literals.

Why am I seeing this error?

Can I simply have it only extract the information and I'll put it in a text
field and have it process the HTML in the same manner to work around this
issue?

TIA
