The minimal example in the README.md is not working

Hi,

The minimal example provided in the README.md

# Import Discord.jl.
using Discord
# Create a client.
c = Client("token"; presence=(game=(name="with Discord.jl", type=AT_GAME),))

# Create a handler for the MessageCreate event.
function handler(c::Client, e::MessageCreate)
    # Display the message contents.
    println("Received message: $(e.message.content)")
    # Add a reaction to the message.
    create(c, Reaction, e.message, '👍')
end

# Add the handler.
add_handler!(c, MessageCreate, handler)
# Log in to the Discord gateway.
open(c)
# Wait for the client to disconnect.
wait(c)

doesn't seem to be working (sure, I am replacing "token" with the real one). I am getting this chain of errors:

The similar example with the same exact DISCORD_TOKEN in Python is working so the the problem is not rooted at the API key.

Hope this issue will help improving the library.

Thank you in advance.
