Invalid format exception using Date field in nested mapping

Elastic Stack Elasticsearch
1

I created a mapping for elasticsearch as below:

Put testindex1

{
  "mappings": {
    "SAX_GROUPED": { 
      "_all":       { "enabled": false  }, 
      "properties": { 
        "key":    { "type": "string"  }, 
        "values": {
          "type": "nested", 
          "properties": {
            "x":    { "type": "date", "format": "MM/dd/yy HH:mm"  },
            "y": { "type": "integer"  }
          }
        }  
      }
    }
}
}

And then tried to put in some values:

{
        "key": "visitors",
        "values": [
            {
                "x": "12/23/13 01:03",
                "y": 123
            }
        ]
    }

I get the following exception:

{"error":{"root_cause":[{"type":"mapper_parsing_exception","reason":"failed to parse [values.x]"}],"type":"mapper_parsing_exception","reason":"failed to parse [values.x]","caused_by":{"type":"illegal_argument_exception","reason":"Invalid format: \"12/23/13\" is malformed at \"/23/13\""}},"status":400}

Please suggest what am i doing wrong when I'm trying to use a date field in a nested field.

Your example works perfectly:

DELETE testindex1
PUT testindex1
{
  "mappings": {
    "SAX_GROUPED": {
      "_all": {
        "enabled": false
      },
      "properties": {
        "key": {
          "type": "string"
        },
        "values": {
          "type": "nested",
          "properties": {
            "x": {
              "type": "date",
              "format": "MM/dd/yy HH:mm"
            },
            "y": {
              "type": "integer"
            }
          }
        }
      }
    }
  }
}
PUT testindex1/SAX_GROUPED/1
{
  "key": "visitors",
  "values": [
    {
      "x": "12/23/13 01:03",
      "y": 123
    }
  ]
}

gives:

{
  "_index": "testindex1",
  "_type": "SAX_GROUPED",
  "_id": "1",
  "_version": 1,
  "result": "created",
  "_shards": {
    "total": 2,
    "successful": 1,
    "failed": 0
  },
  "created": true
}

Index creation was successful and I was not able to put in values using:

{
        "key": "visitors",
        "values": [
            {
                "x": "12/23/13 01:03",
                "y": 123
            }
        ]
    }

Was able to resolve the issue, by using the following structure:

  {"SAX_GROUPED":[
{
        "key": "visitors",
        "values": [
            {
                "x": "12/23/13",
                "y": 123
            }
        ]
    }]
}

Thanks for sparing your time.

Then I think you are doing something wrong. SAX_GROUPED is a type according to your first post.

In the last example it's not a type anymore but an object field.

So even if it works, check that it behaves as you actually would like it to behave.
