Briefly, this error occurs when Elasticsearch attempts to upgrade datafeeds (used for machine learning jobs) to a newer version, but encounters issues. This could be due to inconsistencies in the datafeed configurations or insufficient permissions. To resolve this, you can try re-running the upgrade process after ensuring that all datafeed configurations are correct and consistent.
