Briefly, this error occurs when Elasticsearch fails to delete multiple items in a bulk operation. This could be due to various reasons such as insufficient permissions, incorrect document IDs, or the documents no longer exist. To resolve this issue, you can check the user permissions to ensure they have the right to delete documents. Also, verify the document IDs in your bulk deletion request to ensure they are correct and exist in the database. Lastly, ensure that the Elasticsearch cluster is healthy and functioning properly.
