Exception on /api/v1/feeds [POST]

Start at the /api/v1/feeds POST entry point and trace the NAMEX SOLR FEEDER path that emits the logged Solr delete command and exception. Identify the cleanup needed to prevent these error messages, then verify that the feed completes without the exception and that the relevant logs are no longer produced.
