Error: child "id" fails because ["id" must be a string]

[Ben]

While attempting to create a lobby, I get this error

C:\Users\USER\Documents\DRPC\node_modules\discord-rpc\src\client.js:178
        const e = new Error(message.data.message);
                  ^

    message: 'child "id" fails because ["id" must be a string]'
  }
}

heres my code:

const rpc = require("discord-rpc");
const client = new rpc.Client({ transport: 'ipc' });
const config = require('./config.json');
require('dotenv').config();

client.login({ clientId: config.ClientID }).catch(console.error);

client.on('ready', () => {
    console.log('[DEBUG] Presence now active!')
    console.log('[WARN] Do not close this Console as it will terminate the rpc')
    console.log('=================== Error Output ===================')
    client.setActivity({
            details: config.Details,
            state: config.State,
            startTimestamp: Date.now(),
            largeImageKey: config.LargeImage,
            largeImageText: config.LargeImageText,
            smallImageKey: config.SmallImage,
            smallImageText: config.SmallImageText,
            // use an environment variable to set the matchSecret
            matchSecret: process.env.MATCH_SECRET,
            joinSecret: process.env.JOIN_SECRET,
            spectateSecret: process.env.SPECTATE_SECRET,
            partyId: process.env.PARTY_ID,
            partySize: parseInt(process.env.PARTY_SIZE,10),
            partyMax: parseInt(process.env.PARTY_MAX,10),
    })
    const lobby = client.createLobby(2, 12, {
        id: '1234567890',
        secret: '1234567890password',
    }).then((data) => {
    })
    client.connectToLobby(lobby, process.env.LOBBY_SECRET)
})
