JSON ambiguous call

[Nedss]

Hello !

I tried to run basic_bot.nim code. Unfortunately it is not compile and return an error message after compiling with nim c -d:ssl mycode.nim :

/Users/nedss/.nimble/pkgs/discord-2.3.0/src/discord.nim(107, 115) template/generic instantiation of `async` from here /Users/nedss/.nimble/pkgs/discord-2.3.0/src/discord.nim(121, 35) template/generic instantiation of `%*` from here /Users/nedss/.nimble/pkgs/discord-2.3.0/src/discord.nim(123, 14) template/generic instantiation of `%` from here /Users/nedss/.choosenim/toolchains/nim-0.20.2/lib/pure/json.nim(369, 41) Error: ambiguous call; both json.%(opt: Option[%.T]) [declared in /Users/nedss/.choosenim/toolchains/nim-0.20.2/lib/pure/json.nim(343, 6)] and objects.%(o: Option[%.T]) [declared in /Users/nedss/.nimble/pkgs/discord-2.3.0/src/objects.nim(630, 6)] match for: (Option[system.string])

I put there my code :

import asyncdispatch, discordnim

proc messageCreate(s: Shard, m: MessageCreate) =
  if s.cache.me.id == m.author.id: return
  if m.content == "ping":
    asyncCheck s.channelMessageSend(m.channel_id, "pong")                           

let d = newShard("Bot <token>")
proc endSession() {.noconv.} =
  waitFor d.disconnect()
setControlCHook(endSession)
let removeProc = d.addHandler(EventType.message_create, messageCreate)
waitFor d.startSession()
removeProc()

I work on MACOS (Mojave) 10.14.6 and have the last version of NIM.
