Briefly, this error occurs when Elasticsearch fails to rollup data from the specified source index. This could be due to insufficient permissions, incorrect index name, or the index being closed or deleted. To resolve this, ensure the index exists and is open, check the rollup configuration for errors, and verify that the user has the necessary permissions to perform the rollup operation.
