Hi, I'm migrating from elastic client 7.5.2 to 8.2. From HLRC to RestClient  
I used to create Index template like this:

```auto
PutIndexTemplateRequest request = new PutIndexTemplateRequest(templateName);
        request.source(template, XContentType.JSON);
        AcknowledgedResponse putTemplateResponse = null;
        try {
            putTemplateResponse = restClient.indices().putTemplate(request, RequestOptions.DEFAULT);
            putTemplateResponse.isAcknowledged();
            return putTemplateResponse.isAcknowledged();
        } catch (IOException e) {
            log.error(e);
        }

```

Questions:

1. What is difference between [PutTemplateRequest (java-client 8.2.0 API)](https://artifacts.elastic.co/javadoc/co/elastic/clients/elasticsearch-java/8.2.0/co/elastic/clients/elasticsearch/indices/PutTemplateRequest.html) and [PutIndexTemplateRequest (java-client 8.2.0 API)](https://artifacts.elastic.co/javadoc/co/elastic/clients/elasticsearch-java/8.2.0/co/elastic/clients/elasticsearch/indices/PutIndexTemplateRequest.html) ?  
I see both doing same.

2. I'm using [PutTemplateRequest (java-client 8.2.0 API)](https://artifacts.elastic.co/javadoc/co/elastic/clients/elasticsearch-java/8.2.0/co/elastic/clients/elasticsearch/indices/PutTemplateRequest.html)  
and my template creation fails. I'm using `withJson` to pass template json.  
**Error** :

```auto
[es/indices.put_template] failed: [mapper_parsing_exception] Failed to parse mapping: dynamic template [remark] has invalid content [{"path_match":"*.*remark*","mapping":{"copy_to":["all"],"type":"object"}}], attempted to validate it with the following match_mapping_type: [object, string, long, double, boolean, date, binary]

```

**2.a** What's wrong with the request?  
**2.b** I tried in Kibana dev tools with same JSON... `PUT /_template/eua-cdb1_core_efk_8`

It is success. How come ??

One Last Question 🙂  
It says `#! Legacy index templates are deprecated in favor of composable templates.`  
Which latest Java method should we use ?

\*\*NOTE: Some template creation got success with similar JSON structure.

Please help me with the information or examples
