Hi guys, I'm presenting an error to install the plugin or make a query.

Code:

```auto
@Override
    public XContentBuilder toXContent(XContentBuilder builder, Params params) throws IOException {
    	builder.startObject(simpleName());
        builder.field("type", CONTENT_TYPE);
        startDateMapper.toXContent(builder, params);
        endDateMapper.toXContent(builder, params);
        rruleMapper.toXContent(builder, params);
        multiFields.toXContent(builder, params);
        builder.endObject();
        return builder;
    }

```

Error:

```auto

  "error": {
    "root_cause": [
      {
        "type": "parse_exception",
        "reason": "Failed to parse content to map",

        }
      }
    ]
  },

}

```

Do you have any idea why?

A guess based on:

```
Duplicate field 'recurrent_date'

```

You have a duplicated field?

This is not the same error message that you originally pasted. I guess you changed things in the meantime.

Anyway here the problem is that the generated json is not correctly formed. You are missing something similar to a `}` or a `]`.

Hello, in what way can I print the constructor to see so that the structure is generated and closes me.

I'm trying with:

```auto
throw new IllegalArgumentException("builder.toString:" + builder.toString());

```

but did not print the json string or structure created.

I guess it can't because your XContentBuilder object is not properly closed.

If I still have an error there is and it is so simple. and if I delete "public XContentBuilder toXContent ()" from my code, what difference did it open?

I don't understand the question.

The question is that if you delete from my "toXContent"

```auto
startDateMapper.toXContent(builder, params);
        endDateMapper.toXContent(builder, params);
        rruleMapper.toXContent(builder, params);
        multiFields.toXContent(builder, params);

```

it would be like that:

```auto
public XContentBuilder toXContent(XContentBuilder builder, Params params) throws IOException {
    	builder.startObject(simpleName());
        builder.field("type", CONTENT_TYPE);
        builder.endObject();
        return builder;
    }

```

it works to create the mapper. I do not know if it affects something else as in the results of the query that the plugin should return.
