error: 'class WiFiUDP' has no member named 'beginMulticast'

I want to use fauxmoESP on a Node MCU board. In the Arduino IDE this works without any issues, however, when compiling the same code in PlatformIO, I get the following error:

  fauxmo.handle();
}

Are there any suggestions on how I can make it work in PlatformIO?
