Error on disable data_detection

[sphawk]

I'm trying to disable data_detection via curl.
I delete the shard

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

{
  "acknowledged" : true
}

then

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

["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.

[sphawk]

after delete it's not recreated.
checked with

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

return status 404
