I am developing a Quarkus REST-based application where I would like to display the API on SwaggerUI. Alon with that I would like to display the example schema file on my SwaggerUI.

For the Schema file, I would like to read the contents from External URL. So I am using the external value of the @ExampleObject annotation but for some reason, it does not load the file contents from the URL. It just display:

{
  "additionalProp1": {},
  "additionalProp2": {},
  "additionalProp3": {}
}

Following is the Java Resources file with my Swagger annotations:

import javax.ws.rs.*;

import org.eclipse.microprofile.openapi.annotations.media.ExampleObject;
import org.eclipse.microprofile.openapi.annotations.media.Schema;
import org.eclipse.microprofile.openapi.annotations.parameters.Parameter;
import org.eclipse.microprofile.openapi.annotations.parameters.RequestBody;

@Path("/api")
public class Resources{
    @POST
    @Path("/generate")
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    @RequestBody(description = "InputTemplate",
            content = @Content(examples = {
                    @ExampleObject(name = "Schema Example", externalValue = "https://jsonplaceholder.typicode.com/todos/1")
            }))
    public Multi<String> generateTestData(final Map<String, Object> input){
        return null;
    }
}

Following is the screenshot from the SwaggerUI where its not displaying my JSON file contents:

1. Can someone please explain to me how to add the External JSON file to the example Request Body?

2. Also, is there a way to loop over the list of files present in the external URL path so it can display them one by one in the drop-down? Like if I have a list of files in a GitHub folder, I can give the Folder URL so it can loop over files in that folder and display the contents and name in the drop-down of the Swagger UI?
