Hello, I've upgraded the SolrCloud from 7.6 to 8.8 and unfortunately I got the following exception on Atomic updates of some of the documents.
And in some cases some fields are retrieved with an array of multi values in case the field is defined as a single value. Is there a bug on this version regarding the Atomic updates? And how can I solve this issue? org.apache.solr.common.SolrException: TransactionLog doesn't know how to serialize class org.apache.lucene.document.LazyDocument$LazyField; try implementing
