bot.addChatPattern does not existis anymore when upgrading to mineflayer@4.9 from 4.8.1 It has been tested with the latest version and with 4.10, 4.9, 4.8.1/4.8

What did you try yet?

Downgrading to find exact version that changes this. This problem also persist in all versions above 4.9

Your current code

  const bot = await minecraft.createBot({
    auth: 'microsoft',
    username: process.env.GuildBotEmail,
    accessToken: process.env.GuildBotToken,
    //password: process.env.GuildBotPassword,
    chat: 'enabled',
    viewDistance: 1,
    version: "1.8.9",
    host: "hypixel.net",
  })

  bot.addChatPattern("in_limbo", /You were spawned in Limbo./)
  bot.addChatPattern("guild_chat", regex_guildchat, {parse: true})
  bot.addChatPattern("guild_join", /^Guild > ([\w\d]{2,17}).*? joined.*$/i, {parse: true})
  bot.addChatPattern("guild_left", /^Guild > ([\w\d]{2,17}).*? left.*$/i, {parse: true})
  bot.addChatPattern("guild_member_left", /^(\[.*?\])*.*? ([\w\d]{2,17}).*? left the Guild!*$/i, {parse: true})
  bot.addChatPattern("guild_member_join", /^(\[.*?\])*.*? ([\w\d]{2,17}).*? joined the Guild!*$/i, {parse: true})

most of the unrelated code has been removed and only relevant code is shown.

This is because you are not waiting for the correct event. mineflayer requires you to wait for events like spawn before those functions become available.

Worked before without waiting for that event, so it was defently not mentioned in the changelog

It should not have been working if it did, as createBot() is not a synchronous call, it works asynchronously. As in the examples, all the mineflayer bot API methods (like this one) have to be called after the appropriate event, like connection to server, etc. Should be made clear in the API if not already. Feel free to do a PR to add that note to the api.md
