Good morning,

I'm beginning to work with scripting fields and I have doubts and problems. I have created this index:

```auto
POST /sergi-script/_doc/1
{
  "access": "2023-10-26T00:00:00"
}

POST /sergi-script/_doc/2
{
  "access": "2023-10-26T00:00:00",
  "photo": true
}

```

And now my intention is create an script fields using this info:

1. Get a boolean when the access field is befoire than a date:

```auto
GET /sergi-script/_search
{
  "query": {
    "match_all": {}
  },
  "script_fields": {
    "antes": {
      "script": {
        "lang": "painless", 
        "source": "doc['access'].value.isBefore(params['date1'])",
        "params": {
          "date1": "2023-01-01T00:00:00"
        }
      }
    }
  }
}

```

I have an error but I don't understand the reason ☹

1. Is it possible get a boolean field that returns true (when the field photo exists) otherwise false?

Thanks for the help
