Mbed Simulator Error in LoRaWAN demo

Hi all,

I am trying to develop an app on Mbed Simulator from the LoRaWAN demo (https://simulator.mbed.com/#lorawan). However, when I press the ‘Run’ button in order to simulate my code, an error is triggered:

both async and sync fetching of the wasm failed
abort("both async and sync fetching of the wasm failed") at Error

This error also occurs with the native code of the demo.

I would appreciate any help.
