No id why I cannot access key "id"

Elastic Stack Elasticsearch
1

Hello,
sometimes it seems that Elasticsearch is not running as it should so I have tried to debug it using kibana.

I cannot access the key “id” via:

GET /trend_meta/_search  
{     
    "query": {         
        "constant_score": {             
            "filter": {                 
                "term": {                     
                    "id": "trend9d27baa7-7dbe-4448-891a-814cab9e805f"                          
                }             
            }         
        }     
    }
}

the same request using an underline for the key “id”

"_id": "trend9d27baa7-7dbe-4448-891a-814cab9e805f"

gives me the following result:

{
"took": 1,
"timed_out": false,
"_shards": {
    "total": 1,
    "successful": 1,
    "skipped": 0,
    "failed": 0
    },
"hits": {
    "total": {
        "value": 1,
        "relation": "eq"
        },
    "max_score": 1,
    "hits": [
        {
        "_index": "trend_meta",
        "_id": "trend9d27baa7-7dbe-4448-891a-814cab9e805f",
        "_score": 1,
        "_source": {
            "id": "trend9d27baa7-7dbe-4448-891a-814cab9e805f",
            "liveTime": 60,
                }
            }
        ]
    }
}

Why is it, that I cannot get a response for “id” but for “_id”? Has anyone dealt with such a problem before and is there a way to solve this issue?

Thank you for your help.

Many greetings,

Salvatore

Sounds like a duplicate of Elasticsearch cannot access keys although they are available

Let's keep the discussion there.
