1. I was using the provider account `portal/portal` to get the access token, and then created an appointment with the following curl command. It was successful. And got the location is https://fhir-ehr-code.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Appointment/6634715

curl --location --request POST 'https://fhir-ehr-code.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Appointment' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer xxx' \
--header 'Accept: */*' \
--header 'Host: fhir-ehr-code.cerner.com' \
--header 'Connection: keep-alive' \
--data-raw '{

2. But I could not get the created appointment in the result of the list response. The API request address with filter params is: GET https://fhir-ehr-code.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Appointment?date=ge2025-08-19T00:00:00.000Z&date=lt2025-08-21T17:00:00.000Z&practitioner=12742069

I am confused if there is some misunderstanding that I should pass the practitioner in the `Appointment Creation` request? But it is only allowed for Patient in the actor field.

Expected Result:

The Appointment/6634715 can be fetched in the list result GET https://fhir-ehr-code.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Appointment?date=ge2025-08-19T00:00:00.000Z&date=lt2025-08-21T17:00:00.000Z&practitioner=12742069

Actual Result:

{
"resourceType": "Bundle",
"id": "dd1f9d2f-322d-4066-8953-81da0dbb26fc",
"type": "searchset",
