I'm trying to disable data\_detection via curl.  
I delete the shard

```auto
curl -s -H 'Content-Type: application/json' -X DELETE 'http://localhost:9200/video?pretty'

{
  "acknowledged" : true
}

```

then

```auto
curl -H 'Content-Type: application/json' -X PUT 'http://localhost:9200/video?pretty' -d'{ "mappings": { "date_detection": false } }'

{
  "error" : {
    "root_cause" : [
      {
        "type" : "class_cast_exception",
        "reason" : "class java.lang.Boolean cannot be cast to class java.util.Map (java.lang.Boolean and java.util.Map are in module java.base of loader 'bootstrap')"
      }
    ],
    "type" : "class_cast_exception",
    "reason" : "class java.lang.Boolean cannot be cast to class java.util.Map (java.lang.Boolean and java.util.Map are in module java.base of loader 'bootstrap')"
  },
  "status" : 500
}

```

I've a field "meta" (array of metatags) but sometime a metatag is a date and

```auto
["error"]=>
array(2) {
  ["type"]=>
  string(26) "illegal_argument_exception"
  ["reason"]=>
  string(72) "mapper [meta] of different type, current_type [text], merged_type [date]"
}

```

so I think the solution is to disable date\_detection.  
correct? 🤔

After you delete the index can you check if it has been recreated? Because that is what is looking like what happened, and it's mapping the date field automatically.

after delete it's not recreated.  
checked with

```auto
curl -s -H 'Content-Type: application/json' 'http://localhost:9200/video?pretty'

```

return status 404
