Fhir Chaining Search Parameter Resource

I want to search according to the id of the reference in the extension of the encounter reference in the ChargeItem resource. Why is the search parameter I wrote not working?

Search Parameter;

{
  "resourceType": "SearchParameter",
  "id": "charge-item-encounter-reference",
  "url": "http://dev.genyazilim.com/fhir/SearchParameter/charge-item-encounter-reference",
  "name": "searchByEncounterReferenceChargeItem",
  "status": "active",
  "experimental": false,
  "date": "2024-02-12T00:00:00Z",
  "publisher": "İsmail Can Karataş",
  "description": "Search for Fee Items based on the reference of the referenced visit",
  "code": "encounter-reference",
  "base": [
    "ChargeItem"
  ],
  "type": "reference",
  "expression": "ChargeItem.encounter.resolve().extension('reference').value"
}

It's pretty unusual for servers to support 'resolve()' as part of a search parameter definition. Try using chaining, where you define two search parameters - one on ChargeItem.encounter, and one on Encounter extension.

Also, 'reference' isn't a valid URL for a root-level extension. You need a full URI as the URL for extensions. Only extension is nodes inside a complex extension.
