script_score not working

[r3b311i0n]

Using script_score throws ValueError(Q() can only accept dict with a single query...

{
  "query": {
    "script_score": {
      "query": {
        "match_all": {}
      },
      "script": {
        "source": """
          double weight = 1;
          if (doc['type'].value == 'REVIEW') {
            weight = 1.03;
          }
          return weight * decayDateExp(params.origin, params.scale, params.offset, params.decay, doc['modified'].value);
        """,
        "params": {
          "origin": "2020-10-30T00:00:00", 
          "scale": "30d",
          "offset": "1h", 
          "decay": 0.8
        }
      }
    }
  }
}

I'm trying to convert the above but so far unsuccessful.
