### Description

For a query with params like `"params": [{"x": 1}, {"y": 2}]` running in a JVM with assertions disabled results in:

```
  "error": {
    "root_cause": [
      {
        "type": "x_content_parse_exception",
        "reason": "Failed to build [params] after last required field arrived"
      }
    ],
    "type": "x_content_parse_exception",
    "reason": "[3:19] [esql/query] failed to parse field [params]",
    "caused_by": {
      "type": "x_content_parse_exception",
      "reason": "Failed to build [params] after last required field arrived",
      "caused_by": {
        "type": "array_index_out_of_bounds_exception",
        "reason": "Index 1 out of bounds for length 0"
      }
    }
  }
```

but with assertions enabled:

```
[2023-09-07T13:03:21,434][ERROR][o.e.b.ElasticsearchUncaughtExceptionHandler] [runTask-0] fatal error in thread [Thread-2], exiting java.lang.AssertionError: [params] must configure at least one constructor argument. If it doesn't have any it should use ObjectParser instead of ConstructingObjectParser. This is a bug in the parser declaration.
