Briefly, this error occurs when Elasticsearch fails to execute a failure callback, often due to issues with the cluster state or network connectivity. This could be due to a node being unresponsive or a problem with the cluster’s health. To resolve this issue, you can try restarting the Elasticsearch node, checking the cluster’s health and ensuring all nodes are responsive, or increasing the timeout settings if the operation is taking longer than expected. Additionally, check your network connectivity and firewall settings to ensure they are not blocking the callback execution.
