Briefly, this error occurs when an Elasticsearch node that is not the master node attempts to update the cluster state. This is not allowed as only the master node should update the cluster state. To resolve this issue, ensure that only the master node is updating the cluster state. Check your cluster’s health and configuration. If there are network partitions, resolve them. If the master node is not functioning properly, fix the issues or elect a new master node. Also, ensure that your Elasticsearch version does not have bugs related to this issue.
