I’m doing a reindex and have `waitForCompletion: false` (using Node.js Elasticsearch client). The response gives me a task id, but when I query the task id manually ( /\_tasks/\<task\_id\>) I get a 404:

```auto
“type”: “resource_not_found_exception”,
        “reason”: “task [<task_id>] isn’t running and hasn’t stored its results”,
        “caused_by”: {
            “type”: “index_not_found_exception”,
            “reason”: “no such index”,
            “resource.type”: “index_expression”,
            “resource.id”: “.tasks”,
            “index_uuid”: “_na_”,
            “index”: “.tasks”
        }

```

I can query `/tasks?` and some things come up, but not my reindex task. What am I missing?

Hi @mdo1

If you have the task id execute this query in index .task. If you task exists, it must be save in the index.

Ex: TaskId = 1jX23LruSt-C5FXXMKtegA:628

```auto
GET .tasks/_search
{
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "task.node": {
              "value": "1jX23LruSt-C5FXXMKtegA"
            }
          }
        },
        {
          "term": {
            "task.id": {
              "value": "628"
            }
          }
        }
      ]
    }
  }
}

```

Thanks for the reply, @RabBit_BR abBit\_BR

Hmm... I can do a `GET /_tasks?` and that returns (though not my task), but if I `GET /.tasks/_search` the response is an `index_not_found_exception/no such index` similar to what's in the `caused_by` section of my initial question.

I'm not sure what the difference between the 2 queries is and why it seems like I might not have a .tasks index. I wonder if the .tasks index might be automatically getting deleted.

I figured out what was going on here. I was using Amazon Opensearch to access Elasticsearch and didn't realize that Opensearch blocked access to certain indices, .tasks being one of them.

OpenSearch/OpenDistro are AWS run products and differ from the original Elasticsearch and Kibana products that Elastic builds and maintains. You may need to contact them directly for further assistance.
