To resolve this, you can try the following: 1) Ensure the version of the index matches with the cluster state. 2) Check if the index exists. If it doesn’t, recreate it. 3) If the issue persists, consider restarting the OpenSearch cluster to refresh the state. Always remember to backup your data before making any major changes.
