Hey all,
I'm coding a discord bot and I've coded a function that fetches messages from a channel on discord, but the bot can't read messages. I couldn't solve the problem, can anyone help me?

Error stack tree;

An error occurred while trying to fetch the channels:  TypeError: Cannot read properties of undefined (reading 'messages')
    at file:///C:/Users/Administrator/Desktop/gb-ac-bot/src/utils.js:7:88
    at Array.map (<anonymous>)
    at Object.allMessagesFromChannelList (file:///C:/Users/Administrator/Desktop/gb-ac-bot/src/utils.js:7:53)
    at Object.updateServerInfo (file:///C:/Users/Administrator/Desktop/gb-ac-bot/src/scheduler.js:6:34)
    at Timeout._onTimeout (file:///C:/Users/Administrator/Desktop/gb-ac-bot/src/index.js:53:21)
    at listOnTimeout (node:internal/timers:559:17)

----------

utils.js file;

const allMessagesFromChannelList = async (client) => {
    const channels = global.channels.map(id => client.channels.cache.get(id))

    try {
        const messages = await Promise.all(channels.map(async channel => await channel.messages.fetch({ limit: 50 })))
        return messages.map(collection => collection.map(value => value))
            .flat()
            .filter(msg => msg.author.id === global.botId)
    } catch (error) {
        console.error('An error occurred while trying to fetch the channels: ', error)
        return []
    }
}

------------

The line of code that throws that error (line 7);

const messages = await Promise.all(channels.map(async channel => await channel.messages.fetch({ limit: 50 })))

What I have tried:

I read some articles from the Web, but it was not enough for me to solve the error. So I can't say that I tried a lot.
