I'm getting this error in my log:

```auto
Caused by: java.lang.IllegalArgumentException: Fielddata is disabled on text fields by default. Set fielddata=true on [component] in order to load fielddata in memory by uninverting the inverted index. Note that this can however use significant memory. Alternatively use a keyword field instead.
        at org.elasticsearch.index.mapper.TextFieldMapper$TextFieldType.fielddataBuilder(TextFieldMapper.java:670) ~[elasticsearch-6.5.0.jar:6.5.0]

```

Which I don't understand. For this index we have a dynamic template containing:

```json
{
    "template" : "logs_rikstv_app_log*generic*",
    "order" : 1,
    "settings": {
        "index": {
            "refresh_interval": "5s"
        }
    },
    "mappings": {
        "generic": {
            "dynamic_templates": [
                {
                    "notanalyzed": {
                        "match_mapping_type": "string",
                        "mapping": {
                            "type": "keyword"
                        },
                        "match": "*"
                    }
                }
            ],
            "properties": {
                "@timestamp": {
                    "type": "date"
                },
                "errorid": {
                    "type": "integer"
                }
            }
        }
    }
}

```

If I query the actual index for its mappings I get (subset):

```auto
                "properties": {
                    "@timestamp": {
                        "type": "date"
                    },
                    "@version": {
                        "type": "keyword"
                    },
                    "Exception": {
                        "type": "keyword"
                    },
                    "Level": {
                        "type": "keyword"
                    },
                    "beat": {
                        "properties": {
                            "hostname": {
                                "type": "keyword"
                            },
                            "name": {
                                "type": "keyword"
                            },
                            "version": {
                                "type": "keyword"
                            }
                        }
                    },
                    "component": {
                        "type": "keyword"
                    },

```

So, given the fact that the component field is a keyword type, why am I getting this error? I'm sure there's something I don't understand, any pointers appreciated!

Does your index pattern match more than one index? Is this mapping consistent across all indices matched by the pattern?

It does match multiple, but the error from Elasticsearch is related to the index I've posted the mapping for above as far as I can see. I'll go thru them all to see if there are diffs.

You're absolutely right. There are some type discrepancies. Thanks for the pointer!
