Remove group participants

[pedroslopez]

I've just tested it and it's working for me. Are you sure this is the correct chatId and the client is a part of the chat?

Also, where/when are you calling this? Can you post a more complete example?

[ThiagoCarmona]

The client is part of the group and is also an administrator.

The "participants" property successfully returns the list of participants but I am unable to use the removeParticipants () method. Can you show me how you did it?

This is my code

const { Client} = require("whatsapp-web.js")
const client = new Client();

client.on('qr', (qr) => {
    // Generate and scan this code with your phone
    console.log('QR RECEIVED', qr);
});

client.on('ready', () => {
    console.log('Client is ready!');
});

client.on('message', async msg => {
    if (msg.body == '!remove') {
        let group = await client.getChatById("[email protected]");
        await group.removeParticipants(["[email protected]"])
    }
});

client.initialize();

That example looks good to me. I copied the exact same code and changed the IDs and it worked.

Can you print and post the result of group as well as the result of removeParticipants? Also, I'm pretty sure ids for participants should end in "@c.us", not "@g.us".

[pedroslopez]

What version of the library are you running? It seems it's not able to get Store.Wap, which was an issue before but has since been fixed.

[ThiagoCarmona]

The problem was solved, I started a new project by installing the package again.
