TelegramApiException: Not Found about telegram HOT 2 CLOSED

Thanks for the detailed debug log.
I don't have the time to look at this right now, but here is a few pointers:

• which version of the lib are you using ?
• In the request, I can see POST /botnull/DeleteWebhook HTTP/1.1 this is coming from

  telegram/core/src/com/bot4s/telegram/cats/Polling.scala

  Line 34 in 0e30d39

  request(DeleteWebhook).ifM(

  (I can't see your import, but I would assume that you are using the Polling trait from the cats package. The null in the URL make me think of a missing token (unless you removed it to post it on github).

I think that the null is coming from the System.getenv which is returning null if the environment variable does not exist

from telegram.

I've confused and thought that problem in library, but problem was in my program. Sorry

from telegram.
