Briefly, this error occurs when you’re trying to use the [_parent] field in Elasticsearch 6.x or later versions, which have removed the support for multiple types per index. The [_parent] field was used to establish parent-child relationships between documents of different types in the same index. To resolve this issue, you can use the “join” field to model parent-child relationships, or restructure your data to avoid the need for parent-child relationships. Alternatively, you could use separate indices for each type if the parent-child relationship is not crucial.
