DiscordJS DiscordAPIError[50013]

I want to send a message to a channel here is my index.js

const json = require('./jsonEdit.js');
const discordBot = require('./discordBot.js')
const youtubeAPI = require('./youtubeAPI.js')
const server = require('./httpServer.js')
let intervalId = 0 

let link = ''

const main = async () => {
  var config = json.readJsonFile('./config.json');
  try {
    result = await json.updateData('./config.json', await youtubeAPI.getChannelIDByUrl(config.YOUTUBE_CHANNEL_LINK));
    config = result.config
  } catch (error) {
    console.error('Error updating config:', error);
    config = null
  }
  if(config == null) {
    return
  }
  await discordBot.start(json)
  await server.start(json)
  intervalId = setInterval(() => aprilFool(json), 1000); // Check every second, adjust as needed
  process(json)
  setInterval(() => process(json), config.INTERVAL);
}

main()


async function process(json) { 
  let res = await youtubeAPI.isInLive(json)
  var config = json.readJsonFile('./config.json');
  if(res != null) {
    link = config.MESSAGE.replace("${liveVideoLink}",res.liveLink)
    try {
      discordBot.sendNotif(config.DISCORD_ANNONCE_CHANNEL_ID, link);
      console.log("Message sent successfully");
    } catch (error) {
      console.error("Error sending message:", error);
    }
  }
}

function aprilFool(json) {
  var config = json.readJsonFile('./config.json');
  // Specify the date and time when you want the function to run
  const currentYear = new Date().getUTCFullYear();
  const targetDate = new Date(`${currentYear}-04-01T17:05:00`); // Change this to your desired date and time
  const currentDate = new Date();
  if (currentDate.getDay == targetDate.getDate && currentDate.getHours == targetDate.getHours) {
    // Call your function
    discordBot.sendNotif(config.DISCORD_ANNONCE_CHANNEL_ID, config.MESSAGE.replace("${liveVideoLink}", "<https://www.youtube.com/watch?v=dQw4w9WgXcQ>"))

    // Clear the interval after the function is executed
    clearInterval(intervalId);
  }
}

my discordBot.js

const Discord = require("discord.js");
const reg = require('./regex.js')

var running = false

const client = new Discord.Client(
    {
      intents: [
        Discord.GatewayIntentBits.Guilds,
        Discord.GatewayIntentBits.GuildMessages,
        Discord.GatewayIntentBits.MessageContent

      disableEveryone: false
    }
);

exports.start = async (json) => {
    let config = json.readJsonFile('./config.json');
    return new Promise((resolve) => {

        var regArr = [ 
            { regExp : reg.generateRegexForSuffixes(reg.generateWordVariations("quoi")), reply : "feur" },
            { regExp : reg.generateRegexForSuffixes(reg.generateWordVariations("feur")), reply : "ouge" }
        ]

        client.login(config.TOKEN);
    
        client.on('ready', () => {
            console.log(`Logged in as ${client.user.tag}!`);
            running = true;
            resolve(); // Resolve the promise when running becomes true
        });
  
        client.on("messageCreate", (message) => {
            if(message.author.bot) {
                return
            }
            for (let index = 0; index < regArr.length; index++) {
                const element = regArr[index];
                if(element.regExp.test(message.content)) {
                    console.log(`replyed : ${element.reply}`)
                    message.reply(element.reply)
                    break
                }
            }
        })
    
        // Periodically check the condition and resolve the promise if running is true
        const checkRunning = () => {
            if (running) {
                resolve();
            } else {
                setTimeout(checkRunning, 1000); // Check again after 1 second
            }
        };
        checkRunning();
    });
}

exports.sendNotif = (channelId, message) => {
  try {
    client.channels.cache.get(channelId).send(message)
    console.log("Message sent successfully");
  } catch (error) {
    console.error("Error sending message:", error);
  }
}

all my code woked fine yesterday so i don't know why is there an error (i don't add any permission and here is the link i used to invite the bot https://discord.com/api/oauth2/authorize?client_id=1172365624790499388&permissions=137439464512&scope=bot

the error doesn't occure when i use the function sendNotif() in the main function.
