This setting controls whether Elasticsearch should automatically create an index when a document is indexed into a non-existing index. A negative value is invalid. To resolve this issue, you can either set the value to true, allowing automatic index creation, or false, disallowing it. Alternatively, you can specify a list of index names for which automatic creation should be allowed or disallowed.
