Can't access chatID and username in group chat

[moeindev]

In my case, I can't access the chat id and usernames in group chats, it gives me null value

[elbekD]

can you please provide more details? code example

[moeindev]

for example, if I send a command in a group chat like this: bot.onCommand("/mycommand") {msg,_ -> val uName = msg.chat.username } the usernme will be null but in the Group chats, but in private chats it's not null!

docs for Chat object says: username - Optional. Username, for private chats, supergroups and channels if available. username is not available for private groups, so make it public
