Invalid request error of $extract operation

[tandara0]

I have tried to use the $extract operation, which commented in the https://hapifhir.io/hapi-fhir/docs/clinical_reasoning/questionnaires.html.

For this,

1. I created docker container with image: "hapiproject/hapi:latest"
2. I set hapi.fhir.cr_enabled=true
3. I created Example Questionnaire in the https://hapifhir.io/hapi-fhir/docs/clinical_reasoning/questionnaires.html.

Then I tried variable ways of REST APIs for $extraction operation as below:

1. GET http:https://{base_ip}/fhir/QuestionnaireResponse/$extract
2. GET http:https://{base_ip}/fhir/QuestionnaireResponse/ASLPA1/$extract
3. POST http:https://{base_ip}/fhir/QuestionnaireResponse/$extract
4. POST http:https://{base_ip}/fhir/QuestionnaireResponse/ASLPA1/$extract

I referenced https://hl7.org/fhir/uv/sdc/OperationDefinition-QuestionnaireResponse-extract.html for the APIs.
In all trials, for the body, I use the corresponding Example QuestionnaireResponse in the https://hapifhir.io/hapi-fhir/docs/clinical_reasoning/questionnaires.html.

But all the responses of the trials, have the same "not-supported" error:
One of the example is:

{
    "resourceType": "OperationOutcome",
    "text": {
        "status": "generated",
        "div": "..."
    },
    "issue": [
        {
            "severity": "error",
            "code": "not-supported",
            "diagnostics": "Invalid request: The FHIR endpoint on this server does not know how to handle POST operation[QuestionnaireResponse/ASLPA1/$extract] with parameters [[]]"
        }
    ]
}

I tried the $extract operation to the https://hapi.fhir.org, too.
But I met the same problem.

I tried to all below versions:
http:https://hapi.fhir.org/baseR4
http:https://hapi.fhir.org/baseR5
http:https://hapi.fhir.org/baseDstu3

All the versions have the same error.

HI @tandara0 were you able to solve it? We are also facing the same issue.

This operation is only available if the Clinical Reasoning module is enabled. On the public servers this module has not been enabled so the operation is not supported.
