The version of our Elasticsearch is: 7.8 (Platinum)
I tried to delete some indices by using delete_by_query and I have the following error.
"type" : "cluster_block_exception", "reason" : "index [shrink-index-data-000012] blocked by: [FORBIDDEN/8/index write (api)];"
I also checked that I have enough space and the cluster is green with No unassigned shards.
Why am I having this error? How can I delete those documents in this specific index?
