In case your Tika Extractor throws errors in your Drupal or other application, here's what you can try:

1. Try to Create a new Opensolr Index, in an environment using Solr Version 9, or 7, 6, 5... and so forth. Basically, anything other than Solr version 8.x since that has known issues with the Jetty implementation.
2. Contact us, and we'll make sure to enable Tika in your region, in case it hasn't already been enabled. It could happen that the Tike libraries aren't enabled for your index, in your region yet.
3. Make sure your solrconfig.xml file has this Tika Extraction requestHandler defined:
   

   <requestHandler name="/extract/tika" class="org.apache.solr.handler.extraction.ExtractingRequestHandler" startup="lazy">
       <lst name="defaults">
       </lst>
       <!-- This path only extracts - never updates --> 
       <lst name="invariants"> 
            <bool name="extractOnly">true</bool> 
       </lst>
   </requestHandler>

4. When all else fails, simply book your time with us via Zoom, absolutely free, and we'll make sure everything works as expected.
