Hi Solr users:I encountered the following error when indexing MongoDB data by

The basic problem is that the JDBC driver for MongoDB is returning this
java object type for one of your fields:
org.bson.types.ObjectId
Solr has absolutely no idea what to do with that object, so it's
complaining about it instead of silent;u failing to handle the field.
Your DIH config probably includes SQL statements. You might be able to
modify the SELECT to return a type that Solr *does* know how to handle.
You would need to discuss that with somebody who knows MongoDB's JDBC
driver inside and out.
Your follow-up message indicates that you may have modified some source
code to handle that object type, which would be the other solution I can
think of. You didn't indicate what code you were changing. If you're
satisfied with your solution, awesome.
Thanks,
