I have a index template that I define with strict dynamic mapping.

Now I would like to add a field I have remove template, recreated with dynamic=true but it still gives me error on adding field

'error': {'type': 'strict\_dynamic\_mapping\_exception', 'reason': 'mapping set to strict, dynamic introduction of [field1] within [\_doc] is not allowed'},

But when I go to kibana and check index template it is set to dynamic=true.

it does gives me same error even when I don't have any template set (when I remove it)

how do I add a field?

It'd be useful if you could share an example to replicate what you are seeing.

</div>

First I created index pattern with this

```
PUT _index_template/hou_jobs
{
  "index_patterns": ["hou_jobs-*"],
  "template": {
    "settings": {
      "number_of_shards": 1,
      "number_of_replicas" : "1"
    },
    "mappings": {
      "dynamic": "strict",
      "properties": {
        "@timestamp": {
          "type": "date"
        },
        "elm": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "job": {
          "type": "long"
        },

```

Then I am trying to add a field called field1 but it won't allow.  
hence I did two different test. first remove this mapping and it give me above error.  
then I did create mapping again with dynamic=true and added this field1 in to mix.  
it still gives me same error

```
PUT _index_template/hou_vpmh_jobs_elm
{
  "index_patterns": ["hou_vpmh_jobs_elm-*"],
  "template": {
    "settings": {
      "number_of_shards": 1,
      "number_of_replicas" : "1"
    },
    "mappings": {
      "dynamic": "true",
      "properties": {
        "@timestamp": {
          "type": "date"
        },
        "elm": {
          "type": "text",
          "fields": {
            "keyword": {
              "type": "keyword",
              "ignore_above": 256
            }
          }
        },
        "job": {
          "type": "long"
        },
        "field1:{
           "type": "boolean"
         },
```

</div>

Here's what I did;

```auto
PUT test
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": "1"
  },
  "mappings": {
    "dynamic": "true",
    "properties": {
      "@timestamp": {
        "type": "date"
      },
      "number": {
        "type": "long"
      },
      "word": {
        "type": "keyword"
      }
    }
  }
}

```

And then to test it;

```auto
POST test/_doc/1
{
  "number": 5,
  "word": "test",
  "extrafield": "yes"
}

```

```auto
{
  "_index" : "test",
  "_type" : "_doc",
  "_id" : "1",
  "_version" : 1,
  "result" : "created",
  "_shards" : {
    "total" : 2,
    "successful" : 1,
    "failed" : 0
  },
  "_seq_no" : 0,
  "_primary_term" : 1
}

```

I can't seem to replicate what you are seeing with this.

Sorry I might not have explain properly  
I am talking about creating template

Here is exactly what happens. using your example. it must be some bug or I am doing something wrong

Works - Created template

```
PUT _index_template/test
{
  "index_patterns": ["test*"],
  "template": {
    "settings": {
      "number_of_shards": 1,
      "number_of_replicas": "1"
    },
  "mappings": {
    "dynamic": "strict",
    "properties": {
      "@timestamp": {
        "type": "date"
      },
      "number": {
        "type": "long"
      },
      "word": {
        "type": "keyword"
      }
    }
  }
}
}

```

Works - Put one record to index

```
POST test/_doc/1
{
  "number": 5,
  "word": "test"
}

```

Failed as it suppose to fail, because I don't have extrafield define.  
works as expected

```
POST test/_doc/1
{
  "number": 5,
  "word": "test",
  "extrafield": "yes"
}

```

Now change template to dynamic=true, and added new field called extrafield

```
PUT _index_template/test
{
  "index_patterns": ["test*"],
  "template": {
    "settings": {
      "number_of_shards": 1,
      "number_of_replicas": "1"
    },
  "mappings": {
    "dynamic": "true",
    "properties": {
      "@timestamp": {
        "type": "date"
      },
      "number": {
        "type": "long"
      },
      "word": {
        "type": "keyword"
      },
      **"extrafield"** :{
        "type": "boolean"
      }
    }
  }
}
}

```

This should work Right? because I have extrafield define and mapping dynamic = true but it fails

```
POST test/_doc/1
{
  "number": 5,
  "word": "test",
  "extrafield": "yes"
}

```

ERROR, Even though dynamic=true.

```
GET _index_template/test --> this tells me dynamic=true

{
  "error" : {
    "root_cause" : [
      {
        "type" : "strict_dynamic_mapping_exception",
        "reason" : "mapping set to strict, dynamic introduction of [extrafield] within [_doc] is not allowed"
      }
    ],
    "type" : "strict_dynamic_mapping_exception",
    "reason" : "mapping set to strict, dynamic introduction of [extrafield] within [_doc] is not allowed"
  },
  "status" : 400
}
```

I just did the same thing, but added a `DELETE _index_template/test` before I put the second template, and it worked fine.
