GroupNotification.getChat() does not work in the client.on("group_join") Event #1329

Closed LighteningCode closed 2 years ago

LighteningCode commented 2 years ago

Is there an existing issue for this?

Describe the bug

Seems like the GroupNofication.getChat() function does not work

client.on("group_join", async (notification) => {
  console.log("SOMEONEs JOINED", notification);
  try {
    const chat = await notification.getChat()

    const welcome = "Welcome to the group"

    await chat.sendMessage(welcome)
  } catch (error) {
    console.log("Something went wrong", error);
  }
});

error that is displayed

In the notification, the chatId is "undefined" GroupNotification { id: { fromMe: false, remote: '120783039379794960@g.us', id: '3EB010BEAECF2569DF64', participant: 'xxxxxxxxxxxxx@c.us', _serialized: 'false_120783039379794960@g.us_3EB010BEAECF2569DF64_xxxxxxxxxx@c.us' }, body: '', type: 'remove', timestamp: 1647416043, chatId: undefined, author: 'xxxxxxxxxxx@c.us', recipientIds: [ 'xxxxxxxxxx@c.us' ] } When can get this from notification.id.remote And then send messages const chatId = notification.id.remote; await client.sendMessage(chatId,"Hello Welcome");

Anyone eyes @pedroslopez ....any information?

const chatId = notification.id.remote
const groupChat = await client.getChatById(chatId)

This will get you the chat object so you can work with it. This is what am using

@LighteningCode Is right

That should work, if doesn't, use the one above to send the message.
