How can I fix this, please? Also, using Logstash, and is there a way to prevent this going forward?

Elasticsearch 6.3.2  
Logstash 6.3.2

```

==================================

All of the keyword fields have the ignore\_above setting.

```
    "message": {
      "type": "text",
      "fields": {
        "keyword": {
          "type": "keyword",
          "ignore_above": 256
        }
      }
    },
```
