> [OverseerCollectionMessageHandler::processResponses|https://github.com/apache/lucene-solr/blob/master/solr/core/src/java/org/apache/solr/cloud/api/collections/OverseerCollectionMessageHandler.java#L744]
> structures errors differently in the response, that hides failures from most
> evaluators. RestoreCmd did not receive, nor handle async addReplica issues.
> Sample create collection sync and async result with invalid solrconfig.xml:
> {noformat}
