Hello all,

I am trying to create an index and trying to define mappings for index.  
My Elasticsearch version is 7.3.2.  
Below is the code snippet I am trying.

```json
PUT dish
{
  "settings": {
    "index": {
      "number_of_shards": 1,
      "number_of_replicas": 1

          ]
        },

              }
            },
            "number_facet": {
              "type": "nested",
              "properties": {
                "facet-name": {
                  "type": "keyword",
                  "index": "not_analyzed"

                "facet-value": {
                  "type": "double"
                }
              }
            }
          }
        }
      }
    }
  }
}

```

The output I am getting :

```json
{
  "error": {
    "root_cause": [
      {
        "type": "settings_exception",
        "reason": "Failed to load settings from ..."
      }
    ],
    "type": "settings_exception",
    "reason": "Failed to load settings from ...",
    "caused_by": {
      "type": "illegal_state_exception",
      "reason": "only value lists are allowed in serialized settings"
    }
  },
  "status": 500
} 

```

The error only pops up when i try to have properties in my mappings.  
What could be the reason for this?

`mappings` should be a top-level key in the body instead of a child of `settings`.

Hey Glen,  
Thanks , It worked. I had few more bugs in my code , adding my new code which worked perfectly for future references for someone.
