How to make a rest endpoint / recive json

[thbl]

Hi

I'm new to esp can some one give an example, on how to make a rest endpoint and parse json.
i tried running the sample code

#include "AsyncJson.h"
#include "ArduinoJson.h"

AsyncCallbackJsonWebHandler* handler = new AsyncCallbackJsonWebHandler("/rest/endpoint", [](AsyncWebServerRequest *request, JsonVariant &json) {
  JsonObject& jsonObj = json.as<JsonObject>();
  // ...
});
server.addHandler(handler);

But this just gives me a compile error

   JsonObject& jsonObj = json.as<JsonObject>();

                                            ^

exit status 1
invalid initialization of non-const reference of type 'ArduinoJson::JsonObject& {aka ArduinoJson6120_000001::ObjectRef&}' from an rvalue of type 'ArduinoJson6120_000001::enable_if<true, ArduinoJson6120_000001::ObjectRef>::type {aka ArduinoJson6120_000001::ObjectRef}'

solved just need to replace
JsonObject& jsonObj = json.as();
by
JsonObject jsonObj = json.as();

I found the correct line was
JsonObject jsonObj = json.as<JsonObject>();
