WiFiManager: Incompatibility with ESP32 ESPAsyncWebServer

Basic Infos

Hardware

WiFimanager Branch/Release: Master

Esp8266/Esp32:

Hardware: ESP32 Wroom32

Core Version: tested latest stable and staging

Description

When migrating firmware from using standard WebServer to ESPAsyncWebserver there are conflicts and compile fails

Would be nice if I could still use WiFiManager to provision WLAN and not cook my own!

Settings in IDE

Module: mhetesp32minikit

[env:mhetesp32minikit] platform = espressif32 ; platform_packages = platformio/framework-arduinoespressif32 @ https://github.com/espressif/arduino-esp32.git board = mhetesp32devkit framework = arduino

        request->send(200, "text/html", "<html><head><title>Nooo!</title></head><body>WTF :(</body><html>");
    });
    web_server.begin();

Found yet another “solution”:

include WiFiManager first. ESPAsyncWebServer is already prepared to not redefine the conflicting symbols if the standard webserver is already included.

the bind error remains though…
