You have triggered an unhandledRejection, you may have forgotten to catch a Promise rejection

Recently I went from Node 6 to Node 7 on my server + updating to tmi.js 1.2.1 and I'm noticing these errors regarding promises.

Error log:

17-05-2017 02:06:33 -04:00: You have triggered an unhandledRejection, you may have forgotten to catch a Promise rejection:
bad_timeout_broadcaster

Due to no stack trace I'm not sure where No response from Twitch. is coming from. The one about bad_timeout_broadcaster comes from this:

irc.client.on('notice', (channel, msgid, message) => {
    if (! ['msg_ratelimit', 'timeout_success', 'host_target_went_offline', 'msg_subsonly'].includes(msgid)) {
        console.log(`TWITCH-IRC(notice) Channel: ${channel}. Msgid: ${msgid}. Message: ${message}.`);
    }
});

Where exactly is the promise I need to provide a .catch() to, according to the error message?

tmi.js is only supported by Node 4.x at this time. There is no ETA when we will support Node 6.x and 7.x
