How to get form-field values via Camunda Rest-Api

Is there any way to explicitly get the values of a user tasks form field? I have a form field with three enum values.

enter image description here

When I do the REST call /task/{id}/form-variables I get following output:

{
"pruefungOk": {
        "type": "String",
        "value": null,
        "valueInfo": {}
    }
}

But what i would like to have is something like:

{
"pruefungOk": {
        "type": "String",
        "value": null,
        "valueInfo": {},
        "availableValues": ["ok", "notOk", "helloTest"] <-- Array of the values from first picture
    }
}

Is that somehow possible without doing workaround and dirty code? And why isnt there a REST Call for that?

I know it's a little late, but maybe you will use it some other time or it will be help for some other. What I did is the following:

TaskFormData taskFormData = ProcessEngines.getDefaultProcessEngine().getFormService().getTaskFormData(taskId);

And after that to get the values:

taskFormData.getFormFields()
            .forEach(formField -> {
                if (formField.getType() instanceof EnumFormType) {
                    ((EnumFormType) (formField.getType())).getValues().forEach((key, value) -> {
                        System.out.println("This is the key:" + key);
                        System.out.println("This is the value:" + value);
                    });
                }
            });

Does https://docs.camunda.org/manual/7.13/reference/rest/task/get-rendered-form/ help? I know it is not perfect, but should contain the options.

To extract static information from the bpmn file you can also always resort to https://docs.camunda.org/manual/7.13/reference/rest/process-definition/get-xml/ and then apply e.g. jQuery to the bpmn20Xml in the response.

Please have a look at https://forum.camunda.org/t/how-to-get-form-field-properties-using-rest-api/5981. Looks like the same use case.
