My kibane and es version is 7.8.0  
I create a pipline on kibana dashboard

```auto
{
  "description": "test",
  "processors": [
    {
      "grok": {
        "field": "message",
        "patterns": ["%{DATA:a1} %{GREEDYDATA:content}"],
        "on_failure": [
          {
            "set": {
              "field": "grok_fail_message",
              "value": "{{_ingest.on_failure_message }}"
            }
          }
        ]
      }
      
    },
    {
  "remove": {
    "field": ["log.offset","input.type","_type"]
  }
}
    ]
  
}

```

I get the response:

```auto
{
  "acknowledged" : true
}

```

I found the a1 type is alwyas date , why did appear it:

Look this:

Most likely because the first field that got processed and inserted fit the `date` format and so Elasticsearch automatically created that field as a type `date`...

If you want to make sure keyword or text? Create a mapping ahead of time.

Or you can use the [mutate convert](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-convert) to set the type to `string`

The pipline is ingest node pipline and not logstash pipline; I try to change a1 type is string ,but it't not activate, base on [Convert processor | Elasticsearch Guide [8.2] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/convert-processor.html)

Apologies should have noticed ingest pipeline.

Create a mapping that is the most prescriptive... The same thing is probably happening.. Even though you convert to a string, it has a date format so it's probably getting automatically converted when it's written into a date by [automatic date detection](https://www.elastic.co/guide/en/elasticsearch/reference/current/dynamic-field-mapping.html#date-detection)

You will need to delete the current index because once it's set it won't change.

Explicitly Add the a1 field to the filebeat template as a `text` or `keyword`

If you had run `./filebeat setup -e` per the quick start guide the default filebeat template would have set date `"date_detection": false,` and this would not be happening.

Or you can create a mapping and set `"date_detection": false,`
