I also tried this but it doesn't remove the field parameter as promised. With the following json input:

```
{
"interval":"minute",
"script": "start = doc['recordStart'].value; duration = doc['recordDuration'].value; l = []; for (long i = 0; i < duration; i += 60000) { l.add(start + i); }; return l;",
"field":null,
"lang": "groovy"

```

}

I get the following request

```
 "aggs": {
"2": {
  "date_histogram": {
    "field": null,
    "interval": "minute",
    "pre_zone": "+02:00",
    "pre_zone_adjust_large_interval": true,
    "min_doc_count": 1,
    "extended_bounds": {
      "min": 1366292067758,
      "max": 1433416997446
    },
    "script": "start = doc['recordStart'].value; duration = doc['recordDuration'].value; l = []; for (long i = 0; i < duration; i += 60000) { l.add(start + i); }; return l;",
    "lang": "groovy"
  }
}

```

}

Which gives the following error

```
Error: Request to Elasticsearch failed: (big part removed because message was too long)

```

Failure [Unexpected token VALUE\_NULL in [2].]]; }]"}
