Join VC without being group member

[sayem314]

In desktop and mobile apps, it's possible to do so but not with this library. In order to join a voice chat, it's not mandatory to be in the group.

I haven't faced this. Can you show me your error or something?

[sayem314]

It simply doesn't work. The user won't join but there is no error being generated.

This doesn't make any sense. Are you trying to join the call using the same account?

[sayem314]

Yes. When I'm in the group, everything works fine. I did create a test group of my own so I am sure I am not restricted.

NVM. There was an error message, I tried again now and this error occurred.

Error: Could not find the input entity for {"channelId":"xxx_channel_id_here"}.

Note that when I'm in the group it works without issue. No code changes were made.

Wait I think it's not an issue with tgcalls but mentioned below. GetFullChannel must be called to get details and then use on tgcalls to connect.

          const {fullChat}: Api.messages.ChatFull = await client.invoke(new Api.channels.GetFullChannel({channel})); // here
          if (fullChat.call) {
            try {
              const tgcalls = new GramTGCalls(client, fullChat);
              tgcalls.stream({readable}, undefined, {
                join: {
                  joinAs: 'me',
                  muted: true,
                  videoStopped: true,
                },
              });
            } catch (err: any) {
              console.error(signale.error(err.message));
            }
          }```

Solved now. Fixed via retrieving channel details with Api.channels.GetChannels.
