_ttl mixing up field types issue

Elastic Stack Elasticsearch
1

here is my mapping.

{
  "ultraesb" : {
    "mappings" : {
      "msg_statistics" : {
        "_timestamp" : {
          "enabled" : true
        },
        "_ttl" : {
          "enabled" : true,
          "default" : 900000
        },
        "dynamic_templates" : [ {
          "index_nonanalyzed" : {
            "mapping" : {
              "index" : "not_analyzed"
            },
            "match" : "*"
          }
        } ],
        "properties" : {
          "customFields" : {
            "type" : "nested"
          },
          "recordTime" : {
            "type" : "date",
            "format" : "yyyy-MM-dd'T'HH:mm:ssZ"
          }
        }
      }
    }
  }
}

and when I try to index with _ttl value i get following stack trace

I've tried giving ttl as a string and as a long value as well but I continuously get the same error. Any help is highly appreciated.
