Hi Team,

After upgrading the elastic version 7.17.11 to 7.17.27 we are getting the below error while searching in Elasticsearch.  
our request body size is less than 1 MB, even though we are getting the same exception.  
can you please help to resolve this issue.  
It was working fine in the version 7.17.11

```auto
{
    "error": {
        "root_cause": [
            {
                "type": "parse_exception",
                "reason": "Mustache script result size limit exceeded"
            }
        ],
        "type": "parse_exception",
        "reason": "Mustache script result size limit exceeded",
        "caused_by": {
            "type": "size_limit_exceeded_exception",
            "reason": "String [{ \"_source\" : [\"id\",...] has exceeded the size limit [1073741824]"
        }
    },
    "status": 400
}

```
