Description

All of our schema are Classic, we do no use mutable schemas.
We use the Config API to create /cdcr request handlers

{
  "add-requesthandler":{
    "name":"/cdcr",
    "class":"solr.CdcrRequestHandler",
    "replica": [{
    	"zkHost":"stldeepx20.sial.com:2181/solr",
    	"source":"sial-catalog-material",
    	"target":"sial-catalog-material"
    }, {
    	"zkHost":"stldeepx06.sial.com:2181/solr",
    	"source":"sial-catalog-material",
    	"target":"sial-catalog-material"
    }],
    "replicator": {
      "threadPoolSize":2,
      "schedule": 1000,
      "batchSize": 128
    },
    "updateLogSynchronizer" : {
      "schedule": 60000
    }
  }
}

The actual handler is generated by by an endpoint.
The handler is created, and is functional, but the following errors are present in the log:
