[levlam]

The assertion isn't from TDLib's source code.

[Mashi-91]

[levlam]

You never need to call getSupergroup, if you correctly handle updates. See https://core.telegram.org/tdlib/getting-started for more details.

[Mashi-91]

updateSupergroup — This update is received whenever a new supergroup has been discovered or some data about a known supergroup has changed. This update is guaranteed to come before the supergroup identifier is returned to the Application. So, whenever an Application receives a supergroup_id, it never needs to use the

here i got this.. thnx

and one more thing

can i hide the channel like user can't see the channel?

[levlam]

What channel do you want to hide?

[Mashi-91]

My own channel. Like I don't want to see this channel to user on their chat list.

[levlam]

You can try to hide it only in your own app by implementing the hiding.

[Mashi-91]

can u tell me how?

[levlam]

If you write your own app, then you can skip the chat.

Need Help Brother....

The bug is in your code. You closed the TDLib instance assigned null to the client variable, and then tried to access null object.

[Mashi-91]

No bro, i already checked and Client is not null. I am getting everything except few functions by running those i am getting this error. Like GetMe function works fine

[levlam]

No, it is null. You checked that "Client is not null" only at the beginning of the function, but the function is asynchronous and client isn't a local variable. A lot of other code can run while the function is invoked, including one that closes the client and sets it to null.

[Mashi-91]

If it's null then how does everything works the first time when trigger the function and not work second.. then again work after hot reload. 🤔

[levlam]

That's the question for the rest of your code.
