The command below solved my problem:
$ curl -X PUT “http://127.0.0.1:9200/settings?pretty” -H ‘Content-Type: application/json’ -d ‘{“index”: {“blocks”: {“read_only_allow_delete”: “false”}}}’
{
“acknowledged” : true,
“shards_acknowledged” : true,
“index” : “settings”
}
Thanks to everyone who helped me
