Hi

I don't understand this endpoint but the request structure and syntax seem incorrect . We should organize a call

@NISN-SMALS ,

Hello Nick, if you take a look at https://hl7.org/fhir/R4/operations.html#:~:text=If%20there%20is%20a%20single%20output%20parameter%20named%20%27return%27%20then%20the%20response%20MAY%20be%20the%20resource%20that%20is%20the%20return%20value%2C%20with%20no%20Parameters%20resource.%20These%20kinds%20of%20usage%20are%20discussed%20further%20below. you will see that if you want to return a Questionnaire as a single resource, then you will need to call your output parameter "return". Otherwise, you must wrap them in a Parameters resource.

@NISN-SMALS ,

the parameters you use as input are relatively untyped: FHIR has a datatype Age for instance: https://hl7.org/fhir/R4/datatypes.html#Age For the gender, you could use a codeableConcept bound to to a valueset: https://hl7.org/fhir/R4/valueset-administrative-gender.html...

...or don't use an operation at all, and not put effort to improve that - Please consider that a custom operation is NOT a standard mechanism for this.

(the project can decide whatever they want for implementation. The national standard would need to review this)
