When I try to save object List<Range> using ElasticSearch, I get the following error, but there is no problem saving object Range

Thank you.
This seems to be a bug in analyzing the entity's properties. The Range type is not detected correctly, as it is wrapped in a List. This then causes the Range not being converted correctly into the Elasticsearch representation.
