Encountering "only value lists are allowed in serialized settings" while creating a new index

[Avhirup_Chakraborty]

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.

PUT dish

    "index": {

                }
              }
            }
          }
        }
      }
    }
  }
}

The output I am getting :

{
  "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?

[Glen_Smith]

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

only value lists are allowed in serialized 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.
