TypeError: Cannot read property 'id' of undefined at line 24.

[ghost]

Hello, I am @SevenworksGD's main account. I keep getting an error about it reading the property "id" of undefined on line 24.
Can you help me as soon as possible? Thanks.

require('isomorphic-fetch');

const GD = require("gd.js")

const gd = new GD();

const wait = time => new Promise(resolve => setTimeout(resolve, time));

async function messagesUpTo(user, messageId) {
  if (messageId == null) return user.getMessages(10);
  for (let i = 10;; i *= 2) {
    let fetchedMessages = await user.getMessages(i);
    const index = fetchedMessages.findIndex(msg => msg.id == messageId);
    if (index != -1) return fetchedMessages.slice(0, index);
  }
}

async function messageBot() {
  const me = await gd.users.login({ username: "...", password: "...." });
  let lastMessageId = null;
  while (true) {
    const messages = await messagesUpTo(me, lastMessageId);
    lastMessageId = messages[0].id;
    for (const message of messages) {
      if (message.subject == 'Hello') {
        await user.sendMessage(message.from.accountID, 'Hello', 'How are you');
      }
    }
    await wait(15 * 1000); 
  }
}

messageBot();

That probably means you ran out of messages, you can just continue if you see that messages.length == 0 before accessing messages[0].id.

I get (node:1184) UnhandledPromiseRejectionWarning: ReferenceError: user is not defined when I have messages and (node:4472) UnhandledPromiseRejectionWarning: TypeError: Cannot read property 'id' of undefined when I have no messages.

This is a bug in the package, will fix it when I get a chance.
