NPE in com.codefork.refine.solr.Solr

Trying to reconciliate using Solr as backend leads to a null pointer exception for every query, example:

2022-11-01 11:48:29.865 ERROR 13338 --- [pool-5-thread-3] com.codefork.refine.solr.Solr            : error for query=Monte Cristi

The configuration is simple:

cache.enabled=true
cache.ttl=3600
cache.size=64MB

datasource.solr.name=A Solr Second Level administrative division of Dominican Republic
datasource.solr.nametype.id=/location/location
datasource.solr.nametype.name=Geographic Name
datasource.solr.url.query=http://localhost:8983/solr/iso_adm2_dom/select?wt=xml&df=nombre_provincia&fl=id%20score%20nombre_provincia&q={{QUERY}}&rows={{ROWS}}&sort=score%20desc
datasource.solr.url.document=http://localhost:8983/solr/iso_adm2_dom/get?id={{id}}
datasource.solr.field.id=id
datasource.solr.field.name=nombre_provincia

The solr backend has zero problem responding to the queries:

➜  ~ curl http://localhost:8983/solr/iso_adm2_dom/select\?wt\=xml\&df\=nombre_provincia\&fl\=id%20score%20nombre_provincia\&q\=Monte%20Cristi\&rows=5\&sort=score%20desc

Found the problem, I was running java from another directory where conciliator.properties doesn't exist. A hint would be helpful for those cases.

That's a good idea--I think I can add some logging to warn when the API route for Solr is used but it's not configured. Keeping this issue open for that. Thank you for reporting this!
