Trouble using Jython script as ScriptTransformer

[Kevin Grimes]

Hey all,

I’m running v6.3.0. I’ve been trying to configure a Jython ScriptTransformer in 
my data-config.xml (pulls from JdbcDataSource). But when I run the full import, 
it tries to interpret the script as JavaScript, even though I added the 
language=Jython attribute to the <script> tag. I’ve also added a <lib> element 
in solrconfig.xml for my core that references the Jython jar.

Based on my settings below, can you tell if I’m missing anything?

This is the relevant element in solrconfig.xml:

  <lib path="${solr.install.dir:../../../..}/dist/jython-standalone-2.7.0.jar" 
/>

This is the specific error I’m getting:

Exception while processing: cassini_issEdrs_data document : 
SolrInputDocument(fields: 
[]):org.apache.solr.handler.dataimport.DataImportHandlerException: 'eval' 
failed with language: JavaScript and script:

                myFile = Path('/Users/kgrimes/Downloads/autonav-overlays/' + 
fileName + '_autonav.jpg')
                if myFile.is_file():
                    row.put('OVERLAY_URL',
