Can I use ESPAsyncWebServer over Ethernet ? (Arduino-ESP32 v1.04)

[pataga]

I have a basic EthernetWebServer library example working using SPI interface to ENC28J60. No problem running a simple 'hello world' web server.

I then tried running a simple AsyncWebServer example over Ethernet. I have the Ethernet interface up and an IP address allocated via DHCP. But the AsyncWebServer crashes on the server.begin() call. What else should I be doing, or is there some issue with the AsyncWebServer library working over ethernet ?

Thanks for any pointers ...

#include <SPI.h>
#include <UIPEthernet.h>
//#include <EthernetWebServer.h>
#include <AsyncTCP.h>
#include <ESPAsyncWebServer.h>

byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0x01};
AsyncWebServer server(80);

void setup(void)
{
    Serial.begin(115200);
    while (!Serial)
    {
    }
    Serial.println("\r\nStarting AsyncWebServer on ESP32 enet");

    // Use DHCP dynamic IP
    //Ethernet.begin(mac, ip);
    Ethernet.begin(mac);

    Serial.print(F("Connected! IP address: "));
    Serial.println(Ethernet.localIP());
    delay(1000);

    server.on("/", HTTP_GET, [](AsyncWebServerRequest *request) {
        request->send(200, "text/plain", "Hello, world");
    });
    server.begin();
}

void loop(void)
{
}
