(Discord.js v13) 无法从频道获取消息

Question

Node.js: v16.13.0 | Discord.js: v13.3.1

Hello, I've been getting trying to fetch all the messages from a channel. However, I get the following errors:

TypeError: Cannot read properties of undefined (reading 'cache')

TypeError: Cannot read properties of undefined (reading 'fetch')

My code goes like this:

    if(message.content == "!q test")
{
    const channelS = client.channels.cache.get('880814576692789258')

    channelS.messages.fetch().then(messages => { //<---error here
        messages.forEach(msg => console.log(msg.content));
      });
}

What should I do to fix this problem?
