Polling crash at message with audio

[nikitabessonov]

Hello! First of all, thank you for this brilliant package for developing telegram bots with R 🙏 So, I just tried to catch an update with the audio, bot and I got a crash of polling with the message:

Error in if (handler$check_update(update)) { : argument is of length zero

My code:

library(telegram.bot)
updater <- Updater(My token)

h_audio_add <- MessageHandler(Audio_add, filters = MessageFilters$audio)

updater <- updater + h_audio_add
updater$start_polling(verbose = T, clean = T)

Maybe I did something incorrect, but I have tried all tricks to fix it and no-one was successful. Thank you guys!
