After successfully loading data into my Elasticsearch server (I use `ElasticSearch 6.7.0`), this is the response I receive when I send a `GET` request to the URL `localhost:9200/bank/`:

However, when I send a `GET` request to `localhost:9200/bank/_search`, I get the following error message:

```
{
    "error": {
        "root_cause": [
            {
                "type": "parsing_exception",
                "reason": "Unknown key for a VALUE_STRING in [Name].",
                "line": 2,
                "col": 10
            }
        ],
        "type": "parsing_exception",
        "reason": "Unknown key for a VALUE_STRING in [Name].",
        "line": 2,
        "col": 10
    },
    "status": 400
}

```

1. What does the exception mean?
2. Why does it happen?
3. How can I fix it?

can you provide a **full** reproduction in a gist, that includes the order **all** statements that you issued until this happens?

Thanks!
